We are working on a prototype head with upgraded flow. Our CNC program for these heads proved to be a success in our 2.8 Fiero by squeezing 80+ whp with the right combination of heads, cam, intake and exhaust, but the majority of this power was due to the flow ability of the heads.
We are now combining this awesome flow with bigger valves! Stock valves sizes are 1.72 intake and 1.42 exhaust. The prototype heads will have custom made racing Stainless Steel lightweight valves, 1.85 intake and 1.50 exhaust.
After they are fitted they will be bench flowed on a 2.8 bore and a 3.4 bore before and after the CNC port work, that way if you have either or you will know how much it flows with your specific displacement.
We will keep you posted.
