im pulling my stockers to get a stg2/stg 3 port job done.

i am going to get a 3 angle valve job,port work and was wondering what the biggest valves i can put in them would be. thanks

what would a good stg.2/3 head porting job consist of?

 

You can run 2.02 x 1.60, but they overlap the seats and don't give a gain over 2.00x1.55 valves, which is what I'm using.

I'm not sure how they rate the stages, but I think what you're looking for is a full port of the ports, runners, bowls, and chambers, larger valves, three angle job, milled for higher compression etc.

thanks for the info

 

However 2.02 valves fit just fine in the ImpalaSS Iron heads
