Martin those pics are of freshly bored/honed engines, Your never see a used engine in that condition.

I dont know a lot about these things but can you not get it slighly bored and honed again with new rings to match? While its apart I'd deck/skim the block too to make sure its straight.
No that's is my point, cant feel anything with my finger. Had no probs with compression either..Quote:

Si,
Yeah i can get a honing done then re ring it. I cant see why i'd need to skim it when there was no probs with the hg or anything..
Like he says, to make sure it's straight, however a steel rule and daylight also works for this :)
I know that, but what i mean is... Is it wasn't then the hg wouldn't seal...
I am gonna check it's flatness tho.
to be fair benn i got a head from a friend he said it was a good non porous head and came from a running car,i had it pressure tested and the skim they did was very very light and to be fair after seeing how much had been skimmed i wouldnt bother,cost me £75 for pressure test and skim,if id already knew the head like you know yours i wouldnt bother skimming it its £75 better spent elsewhere in my opinion,ps keep up the good work
i also enquired about the block and was advised by the engine builder that he has only known of a warped block twice in 30 years of engine work
What?Quote:

Yeah just backing up Simps on the fact his thinking is straight, just you don't need to go to those lengths to make absolutely sure its flat and level :pQuote:
