Anyone know the thickness?

[general's servant]

getting ready to install head gaskets but was wondering what the compressed thickness was for victors(stock). Motor came with cometic's but wasn't going to spend two bills for the same kind, so I'm going with stocks.was needing info to degree cam. Please no guesses.

Re: Anyone know the thickness?

well... i used a mic on the old gaskets that i took out of the sy, and stock was 0.070

n/a stock 4.3 is 0.035

i was short on time and money, so i used 2 n/a 4.3 gaskets stacked together, to acheve 0.070

has worked for 2+ years, and 24+ psi of boost.

Measured a new GM gasket taken off my motor at .041. This was a previously torqued gasket, so the .040 spec that's commonly given seems to be right on.

I've got a new one in the wrapper that I can measure as well, if you like.

Re: Anyone know the thickness?

I mic'd my stock gaskets last fall when I did my heads & cam swap. Both the Cometic and the stock Victor Reinz came out right near .040 if I remember correctly. I wish I would have written it down to be sure.

If you are looking for more info on the heads/cam swap I wrote a gigantic thread with tons of info and photos from my swap. http://www.syty.net/forums/showthread.php?t=50970 I also posted photos of the gaskets.

Re: Anyone know the thickness?

Thank you guys just what I was needing to know.Dig don't worry about micing your new ones.never heard of stacking two head gaskets on before but I've sealed leaks with two header gaskets before so I learned two new things today :lol: .As soon as its mobile and I figure out how to send pictures I'll do it :tup:

Re: Anyone know the thickness?

I wouldn't do a double gasket on anything that you wanted performance out of, unless you were trying to fix a previously messed-up block.

Quench/Squish should be kept to less than .045, if at all possible. Unless the block was decked, the single .035 gasket would better than the 2.

honestly when i did it we all laughed, and were taking bet's on how long it would last,....i said 1-2 times into boost, thats it.

24 psi and muliple races/ miles later, this thing just wont give up the ghost! :tup:
