I dont understand from your posts if you changed the thermostat or head gasket and youve mentioned swapping heads

Well he holed a piston a while back i think so i imagine he took the head off and put it on a different bottom end.

Have you done a compression test?

I predict it will blown again as Every ca18et ive known that hasnt had the head skimmed on hg replacement has blown the hg again with a few thousand miles at the most.

ally heads can warp just by taking them off incorrectly. its always advisable to surface a ally head before refitting

i thought that u only had to skim the head if the gasket blows, not if changing it. i have a spare head i can use and swap manifolds

well why did you change the head if the gasket hadnt blown?
