Re: port and polish head (coldbanana1)

Just because a head has been "port & polished" doesn't mean it's going to automatially produce x hp, like an air filter. The shaping of the runners, texture and blending plays a major role. You can have "Corky" with a Dremel, going to town and all you'll get is a bigger hole and no low end power...
What are your goals? Low end or upper rpm power? Upper end with no low end loss? When people label their good P&P, question it a little further.
You can see 8+ wheel hp with the proper porting job, 15+ wheel hp with the installation of +2mm Schrick intake vavles and 20+ wheel with the addition of Schrick 268's.
