How much to shave off the cylinder head.

So I have a 68 225 slant apart for re- ring.

Engine had minimal ridge and seems to be in very good shape.

I had a thought that I can take the head in to shave it and raise the compression.

Is .090 too much for an engine that I'm not planning to change the cam or much other than putting a 2 barrel on it.

Am I right in thinking it never hurts to raise the compression whenever possible or should I not mess with shaving and leave it??
