He has been working on these heads of and for 3 years and here is my final product. he said he was going for the pontiac wide ports theme. he said theres guys making big power with them poncho heads. I think these aught to get the job done. I need to get some valves ordered so I get them on aa flow bench

to me that so often purchased Big $ Stage This/Stage That or SuperPorted heads are purchased completely independent of intake manifolds. The time and money for the most part spent on porting and port matching intakes I think exceeds that of doing the heads. (I might be wrong but putting tricked or ported heads on a motor w/o a matching intake is a waste).

Particularly troublesome are the FEs intake manifold pushrod passages that essentially dictate how much can be removed from the corresponding port wall. Another thing is a significant number of FE Intake Manifolds don't take kindly to seriously opening up ports w/o welding.
Bottom line I can't believe any shop or dealer that does your port work is acting in your best interest if they are not doing intake manifold and heads as a matched set.
JMHO

I just didn't bring it home. And yeah It's got tubes pressed in the ports. And Several hours of work into in to mach the heads as well. He said he did about as much as he can without building up the floors. These heads were on the car already with the the same ports your seeing but the were much very crude and a out of the box victor intake with a dominator adapter choking it down to a 4150 size plentum.
Now that the heads have has alot of clean up work and extra attention to the short turns I thinks it's going to help alot .

and changing the intake plentun from a 4150 that it was and making it to a 4500 with the extra port work is not going to slow me down any.

You may not want to take your heads this far out there but But I already ran 6.35 @ 109mph in the 1/8 with it like that but I could have got lucky.

or maybe he epoxied or welded round aluminum bar stock in the tubes and then (offset) drilled the new pushrod tubes for offset rockers???

Justin, how wide are the ports on your heads?

Thats what my intake looks like but we ony needed to do it to 2 pushrod tubes. I think edelbrock has a "We dont care where the holes fall" attitude because they were all over the place. I have heard stories of people having to do it damd near all of them just to get the push rods to line up. I had a few that are close but should be fine ....I hope

jewel?
I noticed no manifold is used by as many serious racers (often running right along with FE Victors) and tricked in so many different ways. I just enjoy seeing the different paths folks go hopping it up.

zzzzzzzz

and post pics then, If the suspence don't get ya first .lol

Cant wait to see the intake with all the new pushrod tubes installed,and the water passages on the ends may be tough to seal.


If I waited 3 years for those I would be pissed,no mater what they flowed,IMHO the guy screwed those heads up because the pushrod need to clear the ports and the tubes to seal them will block those big ol ports.

Are the rockers heavily offset? Otherwise i'm not sure a 1 7/8" wide port is a good idea. The valves are 2 to 2.1" apart depending on heads. With two halves of a 3/8" pushrod diameter between those centers that leaves 1 5/8" between the pushrods minus whatever wall thickness of tubing (or the intake wall) and any clearance between the pushrod and it. Even my .050" offset rockers only leave room for a 1.5" width on a 2.1" valve center HighRiser.

From what I have marked on it the intake port walls are in the under .250" in places.
