Pistons are 0.020 down the bore and I did use the 0.051 gaskets,
I would have liked thinner but I´m using what I have at hand.
Quench = 0.071.

Hmmm.... effective high side is about .0060"
Gaskets aren't THAT expensive. I'm having to wait almost 4 weeks to get some .0030" Cometics from summit just to keep my quench where I want it at about .0038" - .0040"
I think it's important, but that's just me.

Are you serious? You're compromising a build for the price of a set of head gaskets?

Duke, I understand what you're trying to say, but you need to bone up on your math a little.
.0060" is six thousandths, not sixty thousandths. 0.060" is what you meant.
.0030" is three thousandths, not thirty thousandths. 0.030" is what you meant.
.0038" is three and eight tenths, not thirty eight thousandths. 0.038" is what you meant.
.0040" is four thousandths, not forty thousandths. 0.040" is what you meant.

Oh thanks tech..I'm usually pretty good on math, but I sure screwed up by a long shot there!... Lucky I don't work in a bank! I think (hope) the OP knows where I'm coming from...
Thanks for the correction!!

With the oil problem and now this my car has been unuseable for a year now.
Looking for the "vacuum leak" has cost me four sets of intake gaskets and weeks of waiting.
I do have some 0.015 Fel Pro 1094s but they are labeld as needing an
extra smooth finish.
I could´nt find the 0.015 Victor Reinz gaskets I had before and the next thinnest Fel Pro option is 0.039.
Another option would be an SCE 0.021 gasket weighing in at $92.66 a pair,
then I have to add shipping halfway around the world and duty.

Edit:
So the 0.039 Fel Pros would squeek me into the ball park @ 0.059 Quench.
A couple of those will cost me $150.95.

I always thought "bone up" was an English expression and Americans used "cram".

Anyhows I´ve ordered up the Fel Pros 0.039 gaskets plus another set of intake gaskets.

Well down her in Aus "bone-up" lends itself to more of a phrase of "being a man"
But anyways I would have ordered twenty thou gaskets......Good luck!!!

I just got on the phone to Summit and the gasket
to suit my application is Clevite 0.026, so that´s what I´m getting now.

That's good mate. I'm glad your not using the .051" gaskets with a piston that's .020" down from the deck.. I hope you've ironed out your vacuum issue in the process..

Malc before you put your heads back for the last time here is something I do to confirm whether or not the intake will sit properly on the block.

With the heads just snugged down (not torqued) onto the block with the head gaskets.

Place the intake on the engine with no intake gaskets. The intake should nearly sit on all 4 surfaces. The two intake surfaces and the front and rear rails of the block.

If the intake faces of the heads need cutting then the intake will sit high and you'll have a pretty good sized gap between the bottom rails of the intake and the front and rear rails on the block. More than a .06 gap and I'd think about doing some cutting. This is sometimes the case if the decks of the block have been cut.

If the intake sits on the block and there's a gap between the intake and the intake faces of the heads then the front and rear rails of the intake may have to be cut to drop the intake.

Doing it prior to torquing down the heads will save you a set of head gaskets should you need to make any mods.
