look at the pics of the exuast side springs on cyl 3 the springs are much more compressed i ono if that has anything to do with anything but i ono...

This is what I was refering to, the cam is pushing the rocker arms which are opening the valves, which makes the springs compressed.

yea how many psi should the compression test read? 80 psi i know thats definatly not enough...i have 80 in all cyl except for cyl 2 has 145psi

new head time i guess or block

.....take off the head now to look at the pistons?
