I HAVE A LS3 . JUST UPDATED MY BLOCK TO LUNATI RODS , FORGED PISTONS , BUT NO DISHED PISTONS , MY PISTONS STUCK UP A LIL OVER THE DECK , MACHINE SHOP TOLD ME TO RUN A .53 GASKET , I HAVE THE TURBONETICS KIT AND WAS WONDERING IF I RUN LIKE A .100 GASKET IF THAT WILL HELP LOWER MY COMPRESSION AND BE SAFE ?

THANSK FOR YOUR TIME

YES HE SAID IL BE FINE WITH A .53 COMPRESSED GASKET , WHATS YOUR INPUT ON PUTTING A MORE THICKER GASKET TO LOWER MY COMPRESSION A BIT ??

LSx pistons can ride out of the hole up to .007 I think. Mine are .004 out of the hole using LS9 gaskets (.051 compressed).

You need to know how far out of the hole yours are. What pistons do you have as far as part number goes?

1sick7 · 05-18-2013, 10:24 PM

I TOUGHT LS9 GASKETS WHERE .055

blake-b · 05-18-2013, 10:25 PM

Everything I have read says .051.

litle88 · 05-18-2013, 10:29 PM

Compressed GM MLS gasketz they are like ~.048 iirc

How are you determining compression? What are you coming up

blake-b · 05-18-2013, 10:30 PM

The LS9 gaskets have 7 layers vs. 5 layers so the .003 probably comes from that.

litle88 · 05-18-2013, 10:46 PM

Yes more layers but same thickness as Ls3

1sick7 · 05-18-2013, 11:47 PM

What would you guys think of going with like a 0.100- .125 ?

Going from a stock head gasket to a .100 head gasket would lower your compression about 1.2 points (say 10.7 to 9.5).
