Given that it's a bigport it's probably a US engine -- can tell based on the coloration of the head.... there isn't much oil built up on the cam caps (though there usually isn't on bigports).
Doesn't look like there were any major oil leaks.... except there was a bit of a dizzy leak.
As usual there was an issue with the manifold - there is some exhaust soot built up on the exhaust side.
The valves don't look damaged... but there is definite build up... guessing those are the intake valves and cheap gas was used or the rings weren't exceptional and there was additonal blowby & oil was coming in through the TB/intake.
The head mating surface comparison photo.... comparing to a smallport head.
Thank you for playing our game!!!!!
Also... thank you for the specifics on the head itself. I'm not as educated on the transverse applications as I should be
Being that it is for an AE92 application, then the 5 spoke timing pulleys likely belong with the head.... I wonder... are they 204@.050" 7.5mm lift cams, or are they 198@.050" 7.1mm lift cams
The head surface is indeed compared to a smallport, but the surface shows a DEEP cut, I used that DEEP cut view to show that this head is either uncut, or minimally cut.
It's Amazing... when you are grungie... how much better you look once you've taken a shower......
OST-016 ready for work...
some built up carbon remains, this will be removed as work progresses
and after........ a good cleaning
