ok so i riped out my engine and change the cam and heads and a bunch of other stuff. but its all back togather. my other threads are about opti's but i put a new one in and now i get spark and it pops every onces in awhile when i am cranking i checked the fuel pres, all new plugs and wires. could i have done something wrong

i was woundering if my rockers are to tight and all the valves are open could cause this. im going to do a compression test but wanted to now more possibleties
