i'm putting together your basic street motor.

stock lower new rings and bearings and a 230/236 cam on a 112.
headers, ported intake and larger tb.

i'm porting my own heads and doing an all out job. i've polished the chambers, took out all the sharp corners, narrowed the intakes and flattened the roofs as well as teardroping around the valves.

what i'm not sure about is two things.
should i open the valve seats or stick with stock sizes?
should i spring for a set of ferra's??

not sure what the gains would be on the new valves and if that cam could make use of bigger valves.

thanks,
mike

 

so what? nobody can tell me if i'll gain hp on that cam if i open up to larger valves?
