Shim Head Gaskets

Okay, I think I already know the answer but going to ask the opinions of the low comp guru's here. I've got a 77-78 454 and purchased a Comp Cam XES262 532 lift 224-230 duration. I have a set of shim head gaskets that I could put on the engine but don't really think this will make any difference in how the car runs. It would add a minimal amount of compression so I am of the mindset to save them for the next build. Generic headers, old school edelbrock intake, and 4 speed with 3:55 gears, 69 Chevelle.

Shim gaskets worth the effort??

Thanks,
Durand

Have you considered the quench?
Most blocks are at 25 thou, with the use of a steel shim head gasket at 22 thou you have a 47 thou quench.

If you use a 40 head gasket, you are at 65.
