HELP!!! IDENTIFYING MY HEADS

[boostedwrx]

Hey guys,

just wondering if anyone knows how to identify heads, i have a 1996 gf8 wrx.

my heads have under bucket shims, and two lines through cam shaft stampings, 1 line thru the middle and 1 line towards the end. the valve faces have EH and IH on them.

basically wanting to know what version they may be, (sti, standard, etc)

long story short, brought the vehicle, old owner had motor recond (bottom end) and had heads put on that he knows nothing about..

any help would be greatly appreciated.

cheers

My old version 4 sti heads had the same markings you described on the cam shafts, except L4 preceding the IH and EH (inlet and exhaust I assume)

hope you can see these ok, what a mission,

funky edit - fixed up ya links mate

[ben-jamminn]

When you post a image link, click the button in the middle row on the far left that looks like a picture frame, which does this:

You then paste your link between the brackets if you get what i mean.

Your rocker covers look the same as the ones on my old V4 (1998)

[boostedwrx]

Certainly do,, cheers for the info guys,

and thanks for the fix up,, i couldnt work it out,, pfft beginners ae, lols.

Also any one know the best place to get underbucket shims from,? ;D

[kamineko]

i havn\'t seen these before, but its likely they are v4 sti due to:

shim under bucket = sti

V3 sti having different markings on the cams

96/97/98 twin turbo will have blocked off water/oil lines on the LHS head

anything newer than V4 has a different intake manifold bolt pattern

and that ben-jamminn has identical heads on his V4 sti

what do you mean about the valves?

[boostedwrx]

Was just trying to work out if i had a "mongrel" head on my hands, if you knw what i mean,

Lyk a head with possibly different or wrong valves in it , or camshafts in wrong head set up, sucks ther is no part or id numbers on them to easily distinguish them apart,

i might just have to bite the bullet and keep these ones aside if i cannot work them out, Ive had a few subarus now but likewise ive never seen these heads before,ive even done a bg5 conversion with v2 sti heads and there nothin like this either ,,,,,,,maybe easier to buy a set of sti heads that are genuine to their name off someone reputable.

As kamineko said, they are likely version 4 STi, do they work OK? if it ain\'t broke why fix it

[kamineko]

we can\'t tell you the history of the heads but if they are running OK its quite unlikely someone took the time to make a mismatched cam / bucket / valve / head combo. much more likely they have just been slapped on as a whole.

[boostedwrx]

All good, just doin my home work, ;D,,, everyone\'s help is much appreciated, thank you all. Now to order shims,,

till next tym.

remember, a person who never makes a mistake, has never built anything,

Why do you need to order shims?

I wasnt even going to go there and who knows what size you need if any are needed.

[boostedwrx]

lol,

Think the last owner had engine rebuilt by monkeys, They forgot to put a shim under 1 exhaust valve, and didnt put valve keepers on properly on another, i have retrieved 1 shim from the sump but cannot find the other, so my guess is, its been overlooked at rebuild assembly stage

does any one have some or know where i can order some,, subaru in taranaki seem to have no clue on finding the correct part for me

cheers boosted.

[Guest]

You dont just buy shims dude, you need to measure and then get the correct sizes iirc. Ive never messed any up to need to replace them. Members on here normally help out but you will need sizes.

[boostedwrx]

Yup i realise tht, and just waiting on new digital verniers to measure valve to inside buckt clearance , have measured cam to bucket allready,, jst need to add the two together and wullah, minus .25 clearance for exhaust, wld that b about right?.

[boostedwrx]

Yeeha,, measurements nw takn,,

2.25mm shim,

x1 required

then its boost tym,, ;D ;D

[kamineko]

i\'d measure all of them before placing an order

[boostedwrx]

Hi all, just updating progress on head job lols, all shims moved measured moved and re measured, all valve clearances within 0.02mm, altho i do have 1 exhaust valve at 0.33 wich i think is still to big

also,

if any one can help maybe, has anybody got a couple of shims i could buy, i need 1 @ 2.35mm and ill remeasure the other tommorro, and update again

My local subaru dealer cannot and will not supply shims for my heads without a vehicle vin code to match them ... grrr fustrating. Be ok if i actually had a genuine v4 sti lols,

till tomorro,

[Rosssub]

That 0.33 gap could cause an annoying Tick, at 0.08 oversized. While your doing it, with the rest within 0.02. Do it once, do it well

Interested myself now, with heads off and Cam/Valve changes happening. ;D Will let you know if I find any Part Numbers. I\'m shim over bucket, but will be a start?

Your Subaru Dealer orders Shims by Vin Number, most parts are found with Vin (My OEM suspension Bushes were). He doesn\'t know the Vin for your Heads. Just get any V4 STI Vin to order Shims and tell him to just trust you

[Dacca]

Just out of interest, i asked the local Subaru dealer how much it would cost to set tappets on V3sti,reply-cant be done.

Might as well sell my car then i told them..."well we can do something but cant tell you how much!"
