differences in head gaskets

[Mach 5]

Well Im doing some more research for the new turbo engine setup and found a nice set of cometic head gaskets to use. Now the problem is that the engine is an 89 and the gaskets are listed for a 96- 05. What are the differences in these gaskets and can they be used on an 89 3.1L LHO-LG5 motor? I was thinking of using these because of the boost issue and I had a nice set of felpros blow out on me. If not these what else could I use in place?

 

Thanks

96-05? That's an odd range if they're referring to a 3.1 or 3100. Are you sure that's not for a 3400?

 

Also what's the installed thickness of them?

Something isnt right in that listing.

Be certain to use the 3.622" bore gasket with a 2.8, 3.1 or 3100 block. There are different listings under 3400 and 3500 as well; the difference being bore diameter. Many people have used Gen 1 (iron head) 60 degree gaskets and pistons in Gen 3 (3100, 3400) blocks without any issues.

off Cometics website:

 

1996-05 3.1L 60 Degree V6 LHS 90 MLS/C.O.T. - .051" C5220-051 1 $97.65

1996-05 3.1L 60 Degree V6 RHS 90 MLS/C.O.T. - .051" C5221-051 1 $97.6

 

I just looked on the 60degreev6 website and found that they sell them in all different sizes for $150. For what quench I need I have absolutely no clue.

 

-WrathOfSocrus- Yeah I thinking that should work because some people have inter-changed the top end. I guess the block, bolt holes, and coolant locations are all the same

Did you run the engine lean or something? You really shouldn't have an issue with Fel-Pro gaskets and a stock turbo(or even bigger) unless you get some detonation or there's an issue with the sealing surfaces.

 

Got any pictures of those blown gaskets?

I haven't disassembled the engine as of yet but I will put up a build post. Im basically redoing the entire car. It was misfiring a little bit do to a bad coil and the gapping of the plugs. That could have killed it

I'll vouch for Cometic making a good product. I've run them in almost every motor I've rebuilt with no problems.
