Ok I'm new to the whole o ring block thing for hondas but I know they run copper head gaskets on v8's with o rings. I'm trying to figure out what head gasket to order for my block since I have never seen a copper Honda head gasket. I have seen basic felpro head gaskets hold over 500wph but it was not o ringed. What gasket do you recommend?

 

Generally I have always heard you run a standard MLS type gasket (matching to your bore size obviously) with a copper oring'd block.

The copper headgasket was for when you run a stainless oring'd block and have a receiver groove cut in the head as well to match.

 

call golden eagle and get one of their gaskets

I have an aebs copper o-ringed block bored to 84.5mm. I use a cometic head gasket and Im making over 650whp. Cometic has a lot of options as far as bore and thickness goes and seals very well. Golden eagle is a great option too. Golden eagle is just a stock oem honda gasket machined to your bore size.

 

So any cometic or ge gasket in the correct bore size, any input on thickness for the cometic for high boost on a lsvtec at 9.3-1 ish. The head has been decked twice now I'm not exactly sure how much they shaved off either time. Car will be on ethanol and eventually on a small shot of nitrous if I'm not happy with the power it makes. I'm at altitude and only running a 6262, tuner is guessing it will sip making power around 600 due to the lack of oxygen

 

My block was re-serfaced and so was the head, so we ran a thicker head gasket. I cannot remember exactly what size. I think it was a .040
