ok i have a stock bottom end, its got the hyputectic pistons in it, i think there is 4 valve relief cuts in them. anyways, i got offered some edelbrock performers tonight for a price that i cant pass, however i forgot to ask if they were 1.90 or 2.02 valves. so......ive got an e-cam in this motor. assuming the worst, if they are 2.02's will i have any clearence problems? they are stud mount rockers also, which he sed came with em, forgot to ask what size they were also......but if i had to guess id say 1.7s. am i gonna have any problems? and what could i do to fix it?
