I'm in the thought process of something similar.

I have no clue about the crushed height, but the stock gasket is 1.7 mm and according to some calculations I did a 1 mm of change adds/removes about ...

The car looks okey from the pictures, the interior a bit tatty maybe.

Value: an original car is always worth more. Buy it if you like it and get a good price, not sure what these cars go for where ...

One other silly question most probably. but since the plugs on the NA head are on the exhaust hot side, is it possible to machine the spark plug threads on the inlet manifold side instead of the injec ...
