Impala SS headgasket question
You've only reduced the thickness of the head gasket by .022" (about .017" impact to pushrod length)
That alone should not cause you to use shorter pushrods. (typically sold in .050" increments)
The only way to know for sure is to use a pushrod length checker.
I wouldn't bother with it unless you are also upgrading valvetrain or using shaved heads or a decked block.
(In which case I highly recommend measuring and checking sweep pattens)

mine came out to 7.150 from the stock 7.2,(using 7.1) with the gaskets and the heads surfaced,but what james said ^^^ use a pushrod checker

Sorry old post I know. But what gains could be expected from having the heads decked
.01 and using the impala head gaskets? What would the compression bump up to with a stock motor and these changes.
Thanks, and sorry again for bringin up an old post.

The head gaskets alone would bring your compression up about half a point, and the additional .010" would add another point or two. You'd probably end up around 11:1, but that is purely speculation.
