head skiming/size headgasket/hks f-con!

[nick]

wondering if any1 could help?

ive got some 272cams, ex and in. itbs, and standard size pistons, with pink injectors, in a 16v 4age.

Wot i want 2 know is wot headgasket thinkness would work well with this set up?
A 0.8mm metal trd?
Im also going to port and match the head. But how much should i skim the head by? i think the max. is 0.5mm aint it?!

Another question.....

Before i fit all that stuff, ive got a hks pfc f-con, its set up for a 4agze tho.

Would it work with my standard 4age? im thinking it would over fuel it/run ruff? Tho i gota apexi fuel controller, so i mayb able to adjust to the rite ratio? should i plug it in and see, or is that a bad idea?!

Thank you
Nick
