i just got another head and stamped on it says pr4-6. the one on my teg says pr4-1 is this going to make a diffrence. and is there such a thing to regrind stock ls cams for better perfomance.. serched but couldnt really find anything

 

The head is functionally the same as the one you have and yes you can have the stock cams reground, but considering the low cost of aftermarket LS cams it's silly not to go with new ones.

basically! Why pay $250- $300 for regrinds when new cam cores cost $350.

 

thanks for the info on the cams think i'll go 403 or 404 for my turbo set up. the guy that sold me this head said it might have a 3 angle valve job bu wasn't sure, how can i tell?
