If its a powercore 4 , dont bother , only one to go is the 4.1 .

And yes id say the price is 70% looks/quality 30% performance.

yeah as woggy said like 30% performance but if combined with what boris said port and polish job, HD valve springs a high lift cam and even a High compression piston it will work very nicely, just depends how much you have to spend at the end of the day
