so i thought it may be of some interest during the winter mths. 722 casting, radius clay entry port, 2.15" intake with *30 seat, 1.73" exhaust, *45 seat, on Meaux's sf 600 bench..... These are baseline numbers on a set of ported ra IV heads i just purchased. Meaux is going to do some bowl, chamber, shortturn work, and change to a *45 or *50 intake seat.
int...............exh.
.200 142.3 116.1
.300 199.5 149.4
.400 251.5 179.3
.450 270.4
.500 282.3 202.8
.550 270.0
.600 262.9 219.4
.650 259.2
.700 261.8 226.7
.750 264.5
.800 266.5 232.6


here are some more numbers on the same head, with a warrior intake and 1050 carb attached. I had already done port work to the intake and the carb is a ruperts 1050 methanol.

int.
.200 141.9
.300 195.1
.400 238.5
.450 256.2
.500 270.0
.550 281.5
.600 258.2
.650 255.8
.700 256.2
.750 256.6
.800 258.2

These heads will go on a circle track engine for next year. I will continue to post on the results. Also, i will note that Meaux's bench is a stingy one and does not inflate numbers.

Larry's Bench was one of the benches surveyed for accuracy vs a 3 million dollar bench. His stuff was not stingy but very close to the real deal for accuracy. Good numbers JC.

Keep us informed

Always interested how these iron head deals come out as we are restricted to iron and the challenges it involves

Keep posting the results

Hey JC This is "LouisianaGuy". We spoke some time ago, When are you planning on making a trip back to Mo's place? I know we live kind of far apart here in Louisiana, But I would like to get with you some time in the near future and see if I could get some real Pontiac help when it comes time to Freshen my 455 and swap to a lil bigger cam.
I would also Like to have the #96 heads that I got from Tom V. Put on the flow bench to see what they will do, and maby I could slip you a few green backs to maby up the flow a little more on them...."Tom said they were worked just a small bit and they seem to perform pretty well"
I keep seeing the information you post on Larry's work, and I know he has done a bunch of Poncho stuff, but I cant help but wonder if he is really the best choice for Poncho heads?
I had a set of E-heads that he did for a fellow here in Baton rouge, and I spoke to larry and he said he had worked them to just about the Max he could with out any epoxy or other major work. After I got the heads I sold them to a fellow PY member and he had them flowed on a SF bench and they only went like 290-295 @ .700 This seemed kind of low compared to some of the other Poncho Head porters out there. Any thoughts ?
The numbers you seem to be getting are looking really good however. Keep plugging away.
I need to get my old TA into the 11's with Iron heads, as my best friends Old 69 Mustang recently went 12.66@108 on a Stock Iron headed 393 stroker with no port work, and he is now buying some Victor Juniors, and I want to still be able to stomp him with out hitting the Juice. Need some help here Guys.
Thanks,
Mike "LouisianaGuy"

Good info.

larry is a horsepower guru in louisiana..my southern pals love him..i enjoyed a lunch with him at a dyno session,very sharp guy..he would be the first to tell you it aint all about airflow..his stuff flat works..290 cfm of larrys heads will probably outrun 310 cfm of brand x..jmho

Iron heads = Jim Robertson !!!

I agree that the flow numbers arnt everything, especially in class racing

[TIN TIGR]

i was not saying meaux is alone, just that he does great work..

As you can see the exhaust flows alot already on those heads, and the intake is already much better than the average D port. We had issues with that much exhaust flow on my RAIV heads after porting both sides. In fact on our bench the exhaust would flow 80-90% of that backwards so we had some reversion issues to deal with.Ended up with smaller headers and more intake duration on the cam to compensate. Be interesting to see what Larry thinks of that concept.

[1badkiller]

Revision was one thing that larry mentioned to me when we talked about the E-Heads he had done, the guy put them on his car and had some custom headers on it and then larry did more work on the heads and said he was having revision and scavange problems so he needed to swap his headers :P Any way I wish I could remember who bought those E-Heads from me I would be really interested to know what they are doing right now, they were set up with Roller springs and Titanium retainers if memory serves me correct. And there was a TII intake that larry had also Port matched to the heads, what I thought was a very potent combo for sure....Wish I would have had the money to keep it and not just resale it
JC you gona hook me up with some help on the engine Freshen when the time comes?

He did it to keep velocities in check ,IMO. Unlike other Pontiac porters he looks at flow less than a properly designed port. I have seen this first hand myself working on a set done by someone else. They may flow good, but the speeds are way too high in the wrong places.

I did note the heads had alot of intake reversion as they were not cleaned up when purchased. When larry finishes them, we will discuss a cam profile for the application.

mike, if you want the heads flowed, i am sure larry would be happy to oblige. we will be at pinks in feb. at bell rose, so look us up, if you can make it.

i have not talked much about eheads with larry. i believe he did mention 360s peak on a set of eheads he ported with standard pushrod locations. i know for a fact that he has done a set of eheads on a car i will be driving at pinks. i do not know what they flow tho. the car has went 8.70s. it is a 474 single carb, on gasoline. it made about 770hp on larrys dyno.
