[QUOTE="Sluggie24, post: 15682534, member: 184003"] Do the compression tests of each cylinder. Only need 3 compression strokes per cylinder when taking readings. 3 strokes should give you around 125 psi on a good cylinder. A bad cylinder will most likely be 0 psi or extremely low. Test all cylinders to determine if more than one are bad. After you know which is/are bad, pull the valve cover and look at the valves, springs, cam followers for the bad cylinder. You should be able to see if a spring broke or if a valve is stuck down from being bent. Might have to turn the engine over by hand with a breaker bar on the crank bolt to see those. A bent valve doesn't have to hang open far to do what your engine is doing so you might have to look closely and compare to another good cylinders valves. If it's a broken spring then the heads don't have to come off if you have the proper tools to replace it while the head is on the engine. If the valve is hanging open then the head has to come off. I'm curious. With your aftermarket cams did you install aftermarket valve springs? Were the Pistons fly cut to give the valves clearance? [/QUOTE]
