ok, Jesel say NO to high ports & yes to the edelbrock head? .... ARENT they very close?
anyone have experience with Jesel on high ports?

[Skip Fix]

So how are they made to be able to get to the head bolts? My Crower has a solid bar from one end to the other-in fact I had to use a mill and notch it to go over the studs. Are there separate bars for the end cylinders to be able to get to the bolts/studs to retorque?

As far as I know no one is running Jesel on HP heads. Contact Calvin Hill, I believe he is working with Jesel to get something made up.

It was a trick Jack Gaydosh told me about. Combination of grinding on both the stands and socket a little at a time until socket fits head stud nut. I run a high spring rate with 1.8 rockers but all seems well. IIR Frank G. does this trick also. No big job to keep up with maintenance now.

Skip,

The Jessel is clearance for the head studs in the rocker stands. The top shaft is Jessel, bottom is T&D. The second picture is a prototype of the RAV.

Calvin.....So the "new" Jessel's don't require any mod to get to head stud ??
I've had mine for several years now...

Troy,

I think it depends on the actual configuration, but I do know Jessel tries to make all the installations easy without compromising the quality. The latest V shaft system is really close to the valve cover bolt, they have incorporated a nice radius on the back of the rocker.

Hmmm...I have Crower...any better or worse?

[Skip Fix]

Thanks for the pictures it explains it. My Crowers have a solid bar like the T&D.

Since the question of Jesel/T&D rockers was brought up....My comment/question is with BBC motors I've noticed that Jesels require a bit more oil than a T&D, thus a smaller oil restrictor was used when using T&D's....and if less oil up top =more HP then wouldn't T&D's be better??????
But I'm sure most if not all Pro Stock teams use Jesels so there must be something to them.

So has anyone used one size oil restrictor when using Jesels and *a different oil restrictor when using T&D rockers on there Pontiac? If so what size restrictor and lifter combination are you using?*

I'm using T&D's with a Isky Red Zone solid roller lifters,with NO oil restrictor.....and I'm thinking about putting restrictors in the block when I freshen the motor at the end of the season........Thoughts??

Jason, Why don't you use restricted push rods, then you only restrict to the top end and keep the max oil to the lifter. This is what I do, works good.

Good question! My answer...heck I don't know never really thought about it. I'm currently using 7/16,5/16 tapered ..165 wall mantons. I never really payed attention to the size of the pushrod hole.....I'm still learning
I've been running this current combo for going on my 3rd season and the motor will get freshened at the end of the year and I'm ready to start "tinkering" with it a bit.

Mine are Smith Bros 5/16. I bought them through Butler.

I highly recommend them as they have treated me very well. I am probably a T&D supporter for life because of it.
Always go by their recommended torque specs. I learned that the hard way one time in haste between rounds. If you buy a used set up, I suggest replacing all the studs with new ones as an insurance policy.
Best to you

Steve,

Could you post some pics of your custom Hemi Pontiac shaft rocker system? Would it be available to anyone with M/T Pontiac Hemi heads or just one off for you?

Saw this set-up on a 392 @ the MM this year.

Thanks,
Rob

Jason,
I wouldnt restrict flow to lifters too much do it at pushrods ... just remember too little oil up top cuts life of springs etc.. not enough at lifters hurts them too!!!

The benefit of restricted lifter feed is it allows more to go to mains/rods...

I've found out how to send oil to mains/rods first but havent done it yet...

A bit unconventional and a bit of plumbing... it will likely(should) cut total(both heads) upper flow in half... (both lifter banks and heads end up getting fed from last galley fed with my changes)

But it will be awhile before I get to it. (my block also has the "timed" oil port passages to feed the early rocker stud oiling that could get untimed and put to use oiling rocker shafts ala mopar and FE ford. Dont know that I'll do that or if its needed though)

???s... You got my number.
