Yeah I believe so. Usually it's a 50/50 mix they recommend. Never actually read the warnings. I'm thinking its the timing more and more. Maybe leaning it out and causing it to run hot. Is the 54 block comparable with the 56 head? Do all the holes in both mating surfaces line up? Is the gasket possibly blocking a channel?
