i gotta replace my head gastket on my car.......im running a 81.5 bore.....the last headgasket i used was a stock gsr one(81mm..correct me if im wrong).........

is this not good to use the stock bore gasket...if im running just a little bigger bore.....im wondering if that could have been the problem i ran into with the old one........

if i do need a special headgasket for that bore....can someone please guide me in the right direction as far as company or maybe online shop

all feedback will greatly appreciated

 

You can buy overbored OEM headgaskets from Race Engineering or Golden Eagle. .

 

do you have any idea of the cost........or if that is a big deal for 20 over

 

Get your head milled just a little. Get a 20over headgasket and put it back on. Im pretty sure that was your problem. If you don't got ARP headbolts.. i suggest you get those too. Goodluck.

 

why do you suggest getting my head milled i would think that would raise the compression?.......i already got the arp headbolts...so i should be good there.....

 

Milled just incase it warped. If milled just mill it a little. It will flatten the surface and not higher your compression. Only way to higher compression is if you mill it like .020

 

oh ok.........well i really don't think its warp.....its not like a really bad headgasket problem such as leaking down the block or nothing.....is buring some coolent and i seen some oil in my radiator.

 

It only costs $25 to mill.. better safe then sorry.

 

The stock gasket was designed to handle from the stock 81 mm bore up to 81.5 mm . A stock gasket would be fine for your application. If you need, we have them in stock and ready to ship. Check out our online store at http://www.goldeneaglemfg.com Hope this helps.
