So you need what size HG?? if its .020 over, I have one. Cometic gasket, in package still, I needed 75mm, they sent 75.5mm LMK.

 

Honda makes their stock HG with a 75.5mm fire ring. so they only have to produce 1 HG for all the oversizes they make/recommend. if your fire ring is 75.5 (which i am 100% sure it is) you can use it on your block.

 

reallly??? cause i can not find a 75mm bore cometic ANYWHERE? the asses i got mine from said STD bore. but it gets here says 75.5mm. that would be awesome if i can use it still

 

look on thier website. they only sell a "75.5mm" hg. again honda uses the same HG for .010 and .020 overbore.

bet you paid more for it because they were the only ones with one.

sorry to the op for the thread jack.

 

its all good, i just need to know if that headgasket i got will work on my block that is bored with my z6 head because i am trying to do mini me boost, and this is the only thing holding me back from puting it all together

 

what is the bore of your motor?
what is the bore on the HG?

really measure them though. cause like the other i have a hard time thinking you actually have a stock sleeve block bored .050 over. if you do have a stock sleeve bored out that much, i don't think you will want to boost it. as the dynamic CR would crack the sleeves. shit, even the break in process would probubly be too much for the sleeves to handle.

but anyway a .050 over would mean you had a "76.25" mm bore. your 79 mm HG is 2.75 mm bigger, you can't use that HG. if it was say .5 bigger, then that would be ok. IMO
