231 v6 gaskets

[jimski]

What is the best gasket kit for the engine. Tore the unit down and i must say it is prestine in there. I smoked a ring with too much boost and or knock, remember it was smoking from the valve covers. The engine had 30,000 original miles when i bought it. The cylinder walls still have slight cross hacth marks on them when GM honed the 20+ years ago

Im thinking standard hasting piston rings, rehone the cylinders. Put it back toghether. Any ideals, the bearings look new and like i said the piston walls still have cross hatch marks #3 has slight and i mean slight scuff from bad ring right up the center. I can hone that out.

If you have it tron down - why NOT get the crank polished and install new bearings?

Errr. that's a complete set, not just head gaskets. But yes - piecing them together will be cheaper. I bought the GM headgaskets from them, my preference, and they were really expensive - but again, my preference, and piece of mind.

I'm with you on the GM steel shim HG, those are nice and as you said discontinued bummer.

Slumming Mark? Were those the metal shim type or the later graphite type head gaskets? Nick at Arizona GN is the only one that I know has the stock steel shim gaksets. Does Glen have the too?

That crank and bearings are like new not any damage on them Thanks for that link i like the gm head gaskets also.

Charlie - they are graphite, not all steel - just the fire rings

I hope this is not a stupid question but the head gaskets look so new can they be reused?

You might get away with it, but why risk it? If it was an N/A car - i wouldn't have a problem re-using them.

You tore it down this far - unless you want a high possibility of having to do it again soon - replace them.

True, was just entertaining the ideal

If they're steel shim I might consider it, but head gaskets aren't that expensive compaired to blowing one so why risk it.
