So much wrongness...

H89 has small oval ports, 3 small holes for water heated manifold, standard sized valves

H75 has small oval ports, no holes for water heated manifold, largest valves of any production A-series head

GX has large oval ports, NISSAN JAPAN cast into it on top between the valve springs and the rocker cover (the only head with this feature), 4 large holes for water heated manifold, standard sized valves, double valve springs.

GX ports are not only bigger than the H75/H89, but they sit higher in the head than them. You could bolt a H75/89 manifold to a GX and it would work ok, but GX manifold on H75/89 head wouldn't work as well.

I have all 3 heads at the moment.

10mm spark plug leads?

I'll load the pics to my 'Parts pics for explanations' album and tag you in them. You may have to keep reminding me on facebook because I will probably forget while busy working on other things.

Haha I've got a pair of standard 1200 hubs machined to fit s13 rotors

Haha How long have you owned it? The last 4 or 5 owners never seemed to own it for any longer than 12 months. It's a tidy looking car though.

Standard Hitachi Downdraught carbies work on all standard A-series engines, A10 thru to A15, so it should be fine

Put me on the list for a mild steel intake flange for round port prease

Is it just me, or is it a bad idea to paint the inside of the sump?

Does it have an oval port head Darren?
