i was looking in jegs, and i saw these heads. they are designed for 400+ small blocks. with a 220cc intake port, a 68cc exhaust port. 2.08" intake and 1.60" exhaust. and a 64cc or 72cc option.

more info here:

how would turbochargers like these heads for a 400 small block?

is the I/E ratio about right?

what else is nice about these, is that they are cheap $469.99 iron and $484.00 a peace in jegs.

I think Car Craft flow tested these heads (and scillions of others). The results are on their web page.
