Port molding. 3D model of your porting work

Don’t ask me how many flow tests I did to get there but I did these heads for a friend. He decided to sell them so I paid to much for them but there was no way in heck I was going to let them disappear. They ended up going 9.70’s on my 408 on a worn out .030 over bore at 2860 pounds in my car and 10.12 in my sons car at 3200 pounds. Now on a stock crank 360 he has gone several 6.54@3200 pounds with a small 610 roller cam. Junk open chamber 340 style Edelbrocks. Lol.

Oh, come on, tell us how many flow tests you made.. :)
80-120 per set.. :)
first few - mildly encouraging, next 10 - determination sets in, 10 more - you're pissed, next 5 - you found something, another 5 - this is the worst port on the head, the break through 5 - let that dog eat, try different seat angles - 3 more, I'm tired and I have 7 more to do.
Next week, Exhaust side.
