I doubt any of the head gaskets are perfectly round. I haven't seen any for the LT1 that are.

I meant why deal with it when you can get the Victor Reinz for that price ($15.95 each ). You can't get the MR. Gaskets for $32/pair any more. I see that is the price for each. I bought mine from Summit 3yrs ago.

Damn. I called autozone and they recenty switched, they dont carry victor reinz anymore, he tried a cross refrence number and it came back with a stock thickness. Oh well. I just ordered 2 from CNC-Motorsports.

anyway. Is the quench somehting I need to measure?. or just knowing that my pistons are 10 in the hole and the thickness of my head gaskets enuff?. I was using soft solder to measure my quench ring on my snowmobile. it was not fun. lol

You just have to go by your deck height and gasket thickness.

Try Napa, not autozone.
In the hole and gasket thickness is all you need.

I didn't read the whole thread but I want to bring up something that goes contrary to some of the prevailing "wisdom" here. The idea that you have to have a very tight quench. It aint so. The fact that the thickness of a "typical" gasket is 0.039"-0.041" should tell you something - there really is no point try to get it closer. Unless it is a very unusual app, just zero deck it and use a standard gasket. Blower cars work fine with the piston pretty far down in the hole if deep dished pistons aren't in the budget.

So would you say there isn't much difference between .039" and .049"? (honest question )

Not much, if any from the qunech per se. Of course, with the thicker gasket you lose a bit of compression.

Yeah, a slight compression loss is a given. I'll stop worrying that I bought the wrong gaskets now. Thanks.

Well I just put them .010" in the hole and used a .026" gasket wich comes out to a fairy standard .036" quench. almost the same as with a zero deck and .039" gasket.
