head and deck milling?

[lexcrob]

I guess ill begin this with what ive got here:

.010 feeler gauge fits under in the center of head --cams rotate freely and OEM headgasket seems to be fine*
(measured head height with dial caliper and its never been machined)
Im looking to get a compression bump knowing it will alter cam timing which i will machine cam gears appropriately.

Plan is no mill head minimal* amount and also mill block to get some compression bump NA budget project for now.
IF I COULD ONLY FIND A HIGH COMPRESSION HEADGASKET wanting mls reusable no luck searching for one.

Lasty, im aware of piston/valve caution and will clay it to be shur.
