99FLHRCI Posted February 16, 2011 Report Share Posted February 16, 2011 I am looking at doing a head gasket on my B18C5. It is all stock internals. Any recommendations on brand or thickness? It looks like most of the aftermarket ones are thinner then the factory. Also, I assume I have to take the difference between the gasket I use and the factory gasket and add that to the minimum height after decking? (maximum deck is .2mm so if I use a gasket that is .29mm thinner then factory I should not deck the head at all correct?) Quote Link to comment Share on other sites More sharing options...
Nickey4271647545519 Posted February 16, 2011 Report Share Posted February 16, 2011 I know alot of people like cometic gaskets. As to which thickness though, I'm not sure. Quote Link to comment Share on other sites More sharing options...
DaddyBuiltRacing Posted February 17, 2011 Report Share Posted February 17, 2011 I have a cometic, but if I could do it again I would've went OEM. I would've had to went through Golden Eagle since Honda doesnt offer a vtec hg in 84mm lol. Quote Link to comment Share on other sites More sharing options...
99FLHRCI Posted February 17, 2011 Author Report Share Posted February 17, 2011 I have read about modified factory gaskets using only 1 or 2 layers instead of all 3. Ever heard of this or know how reliable it is? Quote Link to comment Share on other sites More sharing options...
Ef8sirJunkie Posted February 17, 2011 Report Share Posted February 17, 2011 stock is .030 of coarse a 2 layer or 1 layer brings the p2v closer resulting in higher compression. I would run a Honda OEM or Golden Eagle (i have replaced many cometic and will never again ) my oem is holding fine but the golden eagle is a improved version of oem (they use stock but enlarge the water ports or sizing for piston bore. here try this calculator and dont forget to click on B series http://www.zealautowerks.com/index.html Quote Link to comment Share on other sites More sharing options...
Buckeye1647545503 Posted February 17, 2011 Report Share Posted February 17, 2011 When working on honda's Use as many OEM parts as possable and your life will better for it Quote Link to comment Share on other sites More sharing options...
Das Borgen Posted February 17, 2011 Report Share Posted February 17, 2011 go for OEM Cometic is FTL Quote Link to comment Share on other sites More sharing options...
DaddyBuiltRacing Posted February 17, 2011 Report Share Posted February 17, 2011 I have read a lot of bad things about Cometic, but honestly I think it comes down to the installer. Any gasket can fail if installed by a total dipshit lol. So far I haven't had an issue with mine (knock on wood). I have seen people run autozone headgaskets with no issues. Hell I have ran a few with no issues, my dad's crx currently has an autozone hg on it and doesnt have any hg issues. Quote Link to comment Share on other sites More sharing options...

It shows green so I assume they "think" it will be "safe"? They also give the option for 2 layer or 1 layer and they are still both green. My stock setup claims 10.6 and their calculator comes up with 10.8. Any experience with modifying an OEM gasket?

DaddyBuiltRacing Posted February 17, 2011 Report Share Posted February 17, 2011 autozone does not make headgaskets... Ok my bad!! Most people refer to parts bought at Autozone or Advance as Autozone or Advance brand parts. Let me make the change so you can go on with your life, "fel-pro" brand Quote Link to comment Share on other sites More sharing options...

Larry at endyn is a god at machine work and has been racing corvettes back in the 70's and basically invented some of the strongest parts for Honda's.
