Vincent, I do have aftermarket heads, Pushrods are all the same length. The only thing I have changed on engine is the cam. Engine ran fine and valve train was fine until I changed cam.
I cant really go with a thicker head gasket as my heads are cut for o-ring head gaskets. I am not sure they make any thicker o-ringed gaskets.
Engine is not stalling, just alot of rattling and a suspicious sound.
I have ran this cam probably 2-3 hundred miles before I pulled engine apart.
I will try a compression check this weekend.
If that is good I might cart it off to a local mechanic I know to troubleshoot it out...
I realize it is hard to troubleshoot engine problems without hearing them run, but thanks for all the input, any other suggestions would sure be welcome....

Thanks,Brandon........
