Hi,
I will be building a new block in the upcoming weeks, and I want to know if I can use a stock bore 81mm headgasket on a block bored out to 81.5. I thought that I had read here a while back that its ok. I don't want to buy another Cometic if I can help it, and Honda doesn't list overbored hgs (I looked at Majestic)
Thanks

 

Yeah I think your good.

 

yeah u could i got 81.5mm on my block and i use a stock head gasket from honda

 

good, I've had no problems with my cometic but I've read about many horror stories.
Plus they're 90 bucks.

 

yes i believe oem headgaskets are 2mm oversized correct me if im wrong, but ebay gaskets son, 40 dollars full kit shipped and probably come from the same ching chong meow factory as felpro

 

I'm using an 81mm but it hasn't run yet so i can't actually say but it sure looks fine.

 

Eh, normally I would go this route (we are using ebay kit on my brothers Vitara'd Z6) but this is going on my built Ls/Vtec w/Holset. I only want to replace it once.
But you are right, the HG actually looks pretty damn good for a cheapie kit. I was surprised.

 

I got a good ol ching chong gasket set off of ebay, and I looked at the hg and said "I think I will go get a felpro" I got the felpro and it was the same damn gasket....... overall I was impressed with the ebay kit I got.

 

i just bought another ebay gasket kit for my ls (name brand .... evergreen automotive) usually its kabuki but its all the same ---- and evergreen sounds ****

 

the one I got was evergreen automtive too. SO far I have 4 minits of run time on it. It hasent leaked yet......
