well i recently had ma head replaced cuz i broke a cam and a couple cam towers.. and so when i got the new one put on (not new, but from a newer model LS) ma car started going slower. i havnt figured out why. so then i thought for a while wanted to know is if maybe ma old head was ported and polished would the new one take .7 sec off of ma 1/8 mile time??i ran a 10.0 with ma old head, and how with a new head and clutch (both stock..soon to be changed) i ran a 10.7.
cuz when i bought the car it already had a GUDE chip and an overborred throttle body. and also how can i check to see if it has been ported and polished??

thanx. please help me out, i need to make my car fast again
