Cyl 4 misfire, coolant in cyl, holds 65lbs compression, new intake gask, help
Ok so too the head off and along with the gasket being bad, the head was cracked at the #4 exhaust valve and up into the exhaust runner. So I got a set of 520 head for 100$. Are they ok to put on or do I need to stay with the 062's?- Bryyrtw1981
