Im currently in the beginning stages of putting together an all motor non-vtec b20 setup. One question i have is would it be better to get a 3-angle valve job, or buy aftermarket? would i expect around the same gains for either one? (i was looking at crower and ferrea valves) any suggestions welcome...

 

Do they make aftermarket valves for P8R head??

 

If you want to do it right buy both and just go with new stock valves again if no aftermarket valves exist at a better price.
