did he check the head for warpage, this is step 1 on all head off events, with a steel ruler, X done, make a X, first 1 line then the 2nd line for the X
then with feeler gauge, .001' max gap under the steel rule. or it is warped, (the rule is.001" warp per foot of head, length, in every engine builders book in print. for 8 decades.
i think he is not a pro.,.... thermalweld what does that mean , epoxy, what damage, ? where?
if the head has cracks, it must be heated very hot and then tig/mig welded, real welding, nothing else works and for sure lasts.
sounds like you will be installing this engine 3 more times to me. really
find a real machine shop, find one where there is long line of folks, with toyota engine, being fixed and happy customers.
If the head is bad buy rebuilt or take the
head to a real head machine shop, and listen what they say, for lasting repair, forget epoxy. (2000F + temps there)
this junk? ( the magic of replacing engine metal deep inside and engine with bottle of crap)? that? SNAKE OIL !
