Re: Stk valves and port vs Valvejob, 2.02s & no porting Jeff, what you're asking is how much flow gains can be achieved just w/ a competition valve job on a stock head. Most porting shops already back cut & lap the valves when they port heads, never heard of chamfering the chamber side, though.
It might be fun to experiment w/ how much flow (& power) can be gained this way, but it would also be expensive. For most guys, if you're going to spend the money for head work & installation, you might as well spend the $$ for a full port job.
We can argue some more about it tomorrow!

Re: Stk valves and port vs Valvejob, 2.02s & no porting The stock valves are pretty good as well as the valvejob. You'll get far better gains with port work, mostly bowl porting, that by changeing valves, valvejob, etc.
