273 questions...a few of them

i read everything i could find on the cam spec sheet and it says that it is not necessary to degree this cam. it states that this is basically a bolt in and go with their lifters and springs. make sure your crank sprocket is in the right key way, your adjusters are backed out as far as they can go. we know the lifters are right, the pushrods are right, the springs are right. im almost guessing that with crank and cam in time, there really is no reason for any valve to hit a piston, even at 4* retarded or advanced, that is not enough to cause that kind of interference. with the correct springs rated for this cam, i dont think coil bind would really be an issue here either. you have got make damn sure that the timing is set where it needs to be. im thinking now that it almost has to be in the rocker arm adjustments. everything else seems to be right. what are the reasons for a bent pushrod?

cam out of time with the crank ,valve timing
valve to piston contact
valve spring bind
push rod is too long
wrong lifters
excessive lift
rocker bind/adjustment


what else is there?
