If you buy the Great Plains cylinder heads, they will machine them to the right cylinder size but you will have to adjust the size of the combustion chamber to get the correct compression ratio. *Please Note: I have not used these Great Plains heads and in most countries you will have to get "Experimental" registration approval to legally use them. * regards Rob
