Any idea why it cracked a head. A guy I pull with has a stroker and he's been having problems with his heads also.
14+ hours driving with 15w 40 delo in the cooling system, then getting in a race before I could fix it
It got hot, found a bad oil cooler, I pulled the heads, went back with the bigger better studs, new cooler, new hoses, new t-stats, twins, and 5" exhaust before I found it, so I missed it the first time to
then also found a spun water pump impeller. When you use modded heads as we do the removal of aluminum from the ports is not your friend when you overheat it. Leaves less room for error! i should have had the heads checked but I could prove a bad gasket so this ones on me, should have sent them back to Guy and had him check them before putting them back on, oh well, live and learn:thumb:
