Plan is to swap in a 3.4 at some point (was thinking Northstar 4.4, but changed my mind) and figured I would get heads done and have them ready when I am ready to do my swap.
Also, what is the casting nbr for 2.8 heads, seems GM used these engines on everything?
I think user La Fiera can get you CNC ported heads. I believe Will is still trying to sell his Falconer-ported heads. Or you can pay a local guy about 400-600 dollars to port your heads.
