915 heads with 2.02's?

these have straight pushrod holes. I feel very fortunate, they are in great shape and will only need to be cleaned up a little and then good to go. I was gonna mill them .030 and run em on my 318, but I almost don't want to cut them, they are real good heads. I would trade them for some clean 302's instead, they are dime a dozen, and with some porting will do what I want.
