Solid lifters

Re: Solid lifters

It's my understanding that the .018" gasket continued to be used for production for some time after the ...711 was released for service.

I have a set of used ...711s that came off a '70 L-46 and measure .022", but I have seen the ...711 speced at .026".

The only compression of a steel shim gasket is the upset area. The bulk material does not compress inelastically AFAIK, so a new ...711 thickness can be measured by micing an unformed area of the gasket.

I anyone has what they think is an untouched Flint-built SB from '64-up, how about if you measure the gasket thickness? Use feeler gages at the corners.

711=.022,336=.018 stainless steel,631=.016. these are measured on a compressed gaskets

Re: Solid lifters

I will agree on the 3830711 to equal .022 but not a stich more. I can post a pic if anyone has interest to see. Mine read .021 so that's close enough if everyone say's .022.

It would seem like the #336 stainless gasket .018 is a good way to go, are these still available? I assume the #631 is long gone..

Did the 631 gasket have that little hole sticking out when installed?

i was able to get the SS ones in the after market several years ago

Re: Solid lifters

If I remove the heads on either of my cars I will be using them as I want to keep the compression as high as reasonably possible.

Felpro offers a polymer coated .015" steel shim gasket. The coating aids sealing.
