built my oldest sons motor a few years ago,, did an oil lab test to see what it comes back with.
the only thing i know to do is to snug the head bolts down a smidge....
there are no coolant lines on the TB ,,,, so...
but i guess overall its not a bad report for like 45k miles so far
see attahched
oh yeah ,, i remember now,, timing cover has a tiny tiny leak... so................. this spring will redo
