For those interested here's a snap of the GM performance TBI intake for use with vortec heads. Just finished installing it today along with my new vortec heads. Hopefully soon the van will be back on the road causing havic again.

I am still contemplating doing this swap (head & intake) on my van. The pic makes me want to do it.....

What size are the combustion chambers on those heads? so what kind of comp ratio are you gonna have?

I believe they are 65cc, but I didn't check them. The old heads were 64cc which I checked and I calculated 9:5:1 compression.
