I have the below short block coming and need to whack a set of heads on :-

"I have a 2.0lt semi closed deck block, rebored to +.5mm OS with brand new mahle forged pistons, these are low expansion alloy pistons same as OEM, so it will be dead quiet, no slap at all, pistons are brand new stroker pistons, have teflon coatings on skirts, block decks machined, set of brand new 2.5lt rods (spec c rods), STI 2.5 MSR rephased oiling crank, ACL race bearings, all assembled as a short"

What do you all recommend, this will be going in my MY00 Wrx, has to be non AVCS heads....

cheers

avcs heads are fine, just dont run avcs cams.

get the heads ported and flowbenched, they'll perform better then anything factory.

So shimless is the way to go, what heads have this feature

What stace said. Spend the money on some really good ported heads. You can start with any crap as they will all flow the same if ported corectly.

Thanks so far guys, I have to buy some heads, I don't have any yet, or are my MY00 heads okay, and do what you said above.

cheers

Is there anything wrong with running AVCS cams (After blocking all the oil holes) without AVCS?

I was tossing it up between STi AVCS cams and older STi cams, and the AVCS ones have higher lift with the same duration.

all the 01+ (GD) heads are shimless buckets

03 onwards WRX heads are shimless, 02 onwards STi heads are shimless.

01/02 WRX heads are shimmed.

Basically, any AVCS head is shimless.
