Help! 360 with 302 heads no compression

Im going to check in the morning. Thanks. Do you know if 318 and 360 have different push rod lengths. I thought they were all the same
It's more about past services on the head, gasket thickness, valves stem height increases with valve jobs and not all will cut the stem height back to factory tolerance.


Heads milled
Valves faced/ground
Seats ground
Gasket maybe thinner

All that equates to... is the necessity of a shorter push rod.
