I'm using a donor engine, so I can build as much as poss before implanting, not sure so my head is an unknown, although the engine turned by hand for on start, looks pretty clean little carbon build up on pistons and at top of stroke. The head was already removed and has been off for over a year now. I was going to get a quote on rebuilding the head Inc skim, don't know whether new valves or changing cams is worth it if I'm not going big big power. It means not utilising the fact that the stock parts are capable otherwise could have used any doner if I was going swap out cams etc.
this is what evinx had to say on skimming. I dont know if there are any tell tale signs if the engine has over heated.
I think I would like to leave rebuilding the head. Then go sick with the original engine when it's pulled out and I'm full of knowledge and experience. Eventually getting the original engine back for VIN no. to tally.
Or just do it once, do it right and forgot about VIN numbers besides this ones being fiddled with more than macualay culkin.
Funnily it was registered as an turbo when imported which had never been an issue when insuring i just say its not. Its pre-op finally freeing the turbo trapped in an NA body. I don't have a great history of the motor originally it was one owner since import in early 2000s, picked it up in Brighton don't think a member here. someone spent money putting the full jdl kit blended, full respray, two tone logo stitched seats. Oh jeez it had the gariest stick on dash veneer, more like venereal disease. A greeny gold metalic monstrosity, There is still a smallest bit of evidence because I never removed the veneer from glove box handle... a little postage stamp sized horror show.
