Ok, I recently did a compression check on my car, and it turned out i was making only 125 psi all around. I loosened up the rockers and acheived a max of 170-175 all around. When I went to tighten up the valves, I couldnt keep it at 175. With slightly turning in the nut by hand like 1 turn, (rocker arm still really loose) I did a compression check just to be sure, and it would lower to about 125 again. I am doing all of this at work with 3 mechanics helping out. Each suspeced push rod length. I went home and got my older push rods which are 1/8'' shorter and it improved to 150. I called a local speed shop for a even shorter push rod, and the have a push rod that is 1/8'' shorter than my shortest. Before I go pick up some push rods, what else do you think my problem is. Heres what my valve train is looking like...
Cam.....unknown (sounds like performance cam)
Push rods......6 7/8'' hardened pushrods old ones are 6 6/8''
Comp cam 1.6 roller rocker arms
Comp cam dual valve springs
Manley guide plates
