is it legal to zero deck a lt1 350 for stock eliminator? If not how much in the hole do I need to leave the piston.

Total deck with gasket IIRC is .062"

If you had a zero deck you'd need a .062" thick gasket....

That's for a late model EFI LT-1...

The old LT-1's probably have a total deck number that would not be safe to run.....

And with the way that a head gasket usually overhangs the bore, the hot lick is to use the thinnest head gasket that you can and more negative deck.

I guess THAT didn't come out right.
And the way the head gasket usually IS LARGER THAN THE BORE IN DIAMETER, ETC.ETC.ETC.

Wink Re: Decking block

You want to order the gasket bore size AFTER you do the valve job...in the new NHRA.
