Would anyone out there happen to know or where i can find out. The intake runner sizes of Chevy 350 aluminum heads #14101128.
Apparently these are off a 86 or 87 corvette.
We are trying to decide which heads to use. But i can't find the flow numbers for this head.

I believe those heads are 86 - 87 angle plug corvette aluminum with 58cc chambers. I don't know the intake runner volume of these heads but here is some interesting flow numbers. These are not the exact heads but I'll guess they are pretty close.

With full porting I've read numbers of 230 cfm @ 0.500" lift on the intake and about 180 cfm @ 0.500" lift on the exhaust.

IMO ... I think the vortec's will give you better results....but they are not aluminum.
