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
