283 head gasket

ss wannabee · 10-16-2009, 09:17 AM

The .017 number mentioned is the compressed thickness, right? What is the "squished" number when you stack 2 gaskets? I've heard that it's not necessarily .034, or did I hear wrong?

I bought the 3995633 maybe 6 months ago but now are no longer available from gm. Did a little comparison with the 4.0 bore gasket and the difference in compression turns out to be almost nothing, 10.639 to 10.632. Looks like I will stock up on the bigger one.
Thanks for the help
