new to this so bare with me. blew a head gasket so i just put a set of used but resurfaced and tested cast world heads.had some 1.6 comp cam roller rockers and bought new comp cam stock length push rods. only prob was the angle of the 2 center bolts for the intake. ground out the right angle to fit, no leaks and car ran great for about a weak. started running rough. checked the valve train and found a broken spring.replaced it with the head still in the car.car ran great again. got on the gas a little bit started running rough again. no broken springs so i did a compression check all between 140 and 145psi. checked valve springs again just to be sure and found a soft spring(I can push it down by hand.) can anybody help me out with why this keeps happening.
