Was thinkinking about getting my b4 ej206 heads ported and the valves machined oversize. Getting new valves, springs, retainers, guides. And using the sti cams that came with the short block or buying new ones..
Or am i better getting some heads that support avcs
Can anybody chime in with some advice please.

Whats your power goal? AVCS heads will require extra wiring and an ecu that can run it. Getting your 206 heads overhauled isnt a bad idea. Is the car TT or single turbo? If youre taking the heads off you could get some wrx heads from 99 onwards and do a nice single turbo conversion and make proper use of that bottom end

Unless you want to go the avcs route I would keep the tt heads and spruce them up a bit.

My short block came with a 05 sti ecu
Its tt at the moment, ive scouted out some standard wrx parts to go single turbo. While its apart i may aswell and upgade them later
I would like to make my heads strong enough to see some high rpm

Why use wrx heads, is that for the different compression ratio?Whats your power goal? AVCS heads will require extra wiring and an ecu that can run it.

WRX heads wont have all the TT stuff on the passenger side head. Just makes for a cleaner conversion. STi heads have better valve trains from factory generally, shim under generally and better cams . If its just going to be a daily then leave the stock TT heads, plug the TT stuff and chuck it back in

Pretty sure b4 heads are pretty much V6 STI heads with TT bitsWRX heads wont have all the TT stuff on the passenger side head. Just makes for a cleaner conversion.
