Can you mill your head down?

PS. You could always put a little JB weld in the head or on top of the piston to decrease volume. hehe.
I've shaved about .008" off my head and I plan to use a head gasket that is .016 thick in place of the stock .027 thick gasket that comes on these motors, these 2 things will decrease my combustion chamber and add a little extra compression as long as the head I use matches my piston.
I have about come to the conclusion that maybe I just need to get the domed piston designed for my angle plug "Slant" engine and that will resolve my issue with this engine rebuild, I ordered the new piston I have off of ebay from BGF and wouldn't you know it is an odd ball that probably isnt even being used in these engines any more, I wont make this mistake again......!
