im sendin my block to get sleeved at GE and im puttin in arias 83mm 9:3:1 flat top pistons. i need to get a cometic head gasket...i was told to get a .043" thickness and that would drop it down to around 9:1 compression. also im getting my block O-ring will this affect what kinda of head gasket i get? thanks

If that's what they told you to get you should get that one... Good luck

 

thanks....anymore smart people here?

 

You have no problem with the head gasket that you mentioned. Good luck with your build.

 

With your block being o-ringed, use their standard gasket, NOT the HP gasket. The HP gasket has a built in fire ring that is NOT compatible with an o-ringed block
Hope this helps.

i just wanted to verify that the .043 thickness will lower the compression to around 9:1
