    as I recall one of the cylinders went Real bad.. so it’s likely only one of the heads would have been salvaged anyway.

    My experience is that permium fuel runs VERY hot.. are you sure the increase in heat is worth the increase in longevity?

    Well, I’m not sure it burns hotter, but it does help with uncontrolled combustion which leads to detonation/preignition damage…You could always increase the size of the high speed jets by .002″ to combat any extra heat….But, at this point, now that it is running OK, it is best to just sell it as is….
