Can I switch to a higher compression head without making any other engine modifications?

And can anyone verify that this is a Snyder 5.5?

Looks like a stock compression head to me, but I am not familure with Snyders heads. Rod

Pictured is the stock 4.22 head.
Snyder's 5.5 head has a heart shaped combustion chamber.

If I could see the other side, I can tell if it is original but that is not the combustion chamber shape of the 5.5 head. The 6.0 head is kinda similar to that one in shape but the chamber roof is lower.

As for bolting a 5.5 to a stock engine, you should not need to make any modifications as long as the engine is mechanically sound beforehand.

Thanks for the info. Someone's trying to pass this off as a HC head on craigslist.
