just buy some 2litre avcs heads, port and polish and it'll be a winner. |
Really?? Thats unusual!
Were they JDM 01 STi heads? They were AVCS as far as I'm aware. Maybe the Jap 01/02 WRX were AVCS, and export models werent??
Either way, my 02 WRX heads were shimmed. I spat a shim running too much Antilag and swapped over to v8 STi JDM big port heads, which were shimless of course. I had these ported and cleaned up, and fitted bigger non-AVCS cams and my standard non-AVCS cam gears, but with all the AVCS gear still hooked up (mainly to provide oil flow to the cam journals). Works for me
