Grab a die grinder and get to it. Have fun with them. I think they would flow pretty good doing half the work I did. I read someone called them a poor mans ram air head. The ports are taller and the bowl is a little larger than my 1971 # 96's.

I did not see a reason to post that flow sheet. Just wanted to tell the story. Their was a higher flow # at an higher lift. I just told about the 294 cfm at .500 lift because it seemed the most impressive, or should I say inaccurate.

Wonder what a 45 degree seat would do for you.
Awesome numbers, you did a great job.
That is correct on the FPS. Air moving 1 1/2 football fields in one second, unreal. I thought about a 45 degree seat as I know you like and use that. I wanted to stay with what Steve was teaching me.

That intake runner flow is at excellence. As if Oink 1 (Greg Merrick) did the work.
Do you know if 061 and Ram Air II have the same combustion Chamber? ( I see similarity, but observe RA II to have a recessed [dry] plug)
My R 96 A IIs are slated to receive such Intake porting this winter. On the fence with DIY or pay Oink 1.

If I use an RPM intake, I plan to leave the head opening width untouched. The RPM's width is cast narrow so I will try to have the intake exit 1.09 to match the width at the bulge.

Or do you guys think I should widen the intake manifold's ports to 1.13-1.16 and have it match the factory opening of the heads?

I wanted this to be a factual porting thread, not sure if I like the porting work being compared to the oink man.

Here is a site to compare the 061 and ra2

That's a true statement/concern it wouldn't be a fair comparison between the two. On one hand you have Greg Merrick a life time Pontiac builder and arguably one of the best "Pontiac" head porters in the world. On the other hand you have "A" guy from Iowa that ported "A" set of heads. I agree there's no comparing the two. JD
