Round port header gasket recommend
 

Looking for header gasket recommendation. 2" round port hedmann e heads. Gaskets I got from butler already leaking center ports and rear on ds. Because race setup not wanting to goop up w sealant. Thinking may have better luck w copper or aluminum style gasket.

I've had Fel Pro's on mine for the last four years. It's been just fine so far. ohh yeah, mine is round port E heads with Hooker super Comps.

I've had great luck with Remflex.

Copper sucked for us. Leaked everywhere. We've used felpro for the last 3 years. No leaks. Mad dogs w/E heads. We used copper sealant to glue to header. Now we take them on and off all the time with no issues. Same gaskets for 3 years.

check out percys, they have been great for me

Are you using Remflex on the turbo car ? .... and stainless flanges, right ?

Do the gaskets expand with heat? I've read that they require little to no torque on the header bolts/studs.. What's your take on them in general?

I am, though mine are d-ports and still on the first set installed in the car. I tightened them like I would a normal header, checked to see if they loosened up a couple times but all was good so I stopped checking. They compress quite a bit, not sure about expanding. I was so pleased with them I recommended them to my buddy after he lost 2 sets in his Pontiac powered Chevelle and that was the last set he bought. Everyone says they're definitely not reusable, but until you break the seal they work great! I'd give them a try.

Thanks, going try copper sealant, a lot of gaskets too small for 2" tubes

X2 on Remflex. Expensive but they don't leak!

I've had good luck with Ultra Gray sealant. Color matches the heads and not bad to get off if you need to remove the headers and reinstall.

Remflex...

I use copper RTV with good luck and it's cheap.

In the big scheme of things...they are cheap!Guys spend way more money on fluffy showy parts that aren't needed.

I have reused the same Fel Pros over and over

I sure would be nice if someone made us a heads gasket in dead soft aluminum.

Amen! And they're cheap. Unlike remflex that can't be re used

X2.

I have used the Fel Pro Race gaskets and they work just fine. The Mr Gasket race are ok. The worst are the plain white cheap ones you get with your Hooker headers. The center ones always blow out.
Currently I have copper in the center ports and old Fel Pros on the outside.
Maybe the iron HO heads help with the copper not leaking. Biggest problem I have ever had was the driver side #8 ear that "sticks out in the air" rusting itself in the head and rounding off. Believe me, heating the ear up red hot with a torch and using brand new Vice Grips was not fun. Took about 5-6 tries at it. Beoing a welder you know heating up cast iron to that extent, with the rest of the iron not being so hot creates a heat line and it can....... crack. But all ended up OK.
Now I run the ARP stainless header bolts with the 5/16 heads on the ones that stick "out in the air". They are very smooth and dont seem to stay as tight as carbon steel bolts but I am not going through that again. On all the very outside exhaust bolts, the ones that end up with iron on the backside I just run plain grade 8 bolts with 9/16 heads. They always come out.
These expensive Remflex, how expensive are they ?

Re-tight the header bolts seems to fall on deaf ears ?
Hey, I'm missing a header bolt. When did that fall out ?
Guess where !

I like Remflex gaskets.

I did blow one out one time, but it was clearly my fault. Didn't get nearly enough "crush" on the center 2 exhaust ports on a set of "6X" heads (because d port heads and headers/bolts are a PITA). Replaced the gasket and got it tightened down enough the second time, never another issue.

I use the felpro performance header gaskets, because they seal good and do not leak. Years ago when I was running D-ports I was able to reuse them many times. Recently I installed some new felpro performance round port header gaskets and had to remove the headers for maintenance shortly after installing them, and the gaskets split, unlike in the past when they came off in one peice and were reusable.

I cut my gaskets in 3 pieces before I install them. That way when I take them off, some or all of the gaskets are still usable. I hang the good ones that I dont end up using on a nail on the wall in the garage. That way I have "extra" just in case. I do the same thing with intake gaskets. I use some Aviation around the intake runners as it does not harden and #2 around the water crossover part. They still rip most of the time coming off. But I save that little coolant crossover part from used ones or just some cheap generic intake gaskets on the same nail. My intake and header gaskets are a "mix" most of the time.
You never know. Might get caught on a Saturday nite late with a race on Sunday.
Saved a few Pontiac racers day at the track doing this when they had issues. Had a quick fix for them.

I have been using remflex also no issues.

Have Remflex on the street cars, but haven't put them on either of our drag cars because don't want the expense or the time needed to scrape them off the heads and headers. There was only one time that we were able to remove a set without them coming apart, but the other half dozen times they have separated at the screen center portion with half sticking to the header and half to the head. I plan to run for years with the street cars, but just maintenance on the drag cars says they will be coming off at least at the end of the season. I've come across missing bolts and many loose bolts without the Remflex blowing out or even leaking, and that's something we've never accomplished with any other brand.

Remflex work great, but you have to be very careful when installing headers, as they damage very easy. They are like a thin water cookie.
I put it on the head, then cover it with another paper type gasket to protect it while aligning the header. Once lined up just slide out the paper gasket.

Another vote for Remflex. Never had a header gasket seal like them!
