Well I guess we'll never know for sure but there were no signs of excessive EGT's. Pistons showed no pick-marks/melting typical for lean mixture (actually I believe piston survived but was binned beacuse of ovality). Head just exploded...clean break edges, no melting. It's somewhat atypical operating range for OEM 3.6 head though...
Thank you for your time,
