ARP head bolts question (SR20)

[decksy]

so i finally could afford arp headbolts for my sr, and i was wondering if i installed them on my car now.. would it mess up my greddy metal hg thats already on it? or did i just ask a really stupid question and it wont effect anything?

love always

technically if you remove them one at a time from the middle and work out.. IE remove bolt, insert stud, torque down.. repeat. You probably will not mess with your head gasket sealing. No you won't warp your head either.

backwards. When taking off, u want to work from outside in.

It's a mute point because he's untorquing and retorquing one at a time. Direction doesn't really matter. A mls gasket also should reseal if he did them all at once but I hate breaking the seal ;)

Stick with the stock head bolts with a greddy head gasket. You can even call greddy on this one ( beyond my personal experience. ) If you are having head gasket sealing problems then replace the HG with a Power Enterprise. If not then don't mess with it until you do. From experience, greddy HG's suck for heat resistance. If you overheat the motor slightly once be prepared to change the HG.

the saying "If it isn't broke, don't fix it." applys here.

how is apexi's headgasket?? have you had any experience with those?

[SoSideways]

RS-Enthalpy recommends the Apex'i HGs over the Greddy HGs if that tells you anything. Actually, Enthalpy had a Greddy blow up on his on a shake down run, that's how bad they are. They're bad because the bore diameter on their HG is too big for the stock SR bore. The Apex'i HG has a bore diameter of 87mm IIRC, and the Greddy has like 88mm.

So yeah, when it's time to upgrade my HG, I'm going with Apex'i.

Apex'i is prolly the best out there rite now. Then PE. But yah, honestly, you dont need the ARP headstuds. Unless youre running some crazy amount of hp *close to 500hp* then yah go for it or if your stock bolts are stretched out of spec. Like said, if it aint broke, then dont try to fix it.
