The 64cc head will drop your compression. There are Vortecs for the 305 and I believe they are 58cc.I intend to live forever; so far, so good.

Yep, I am going to put a set of 305 Vortecs on my 350 vortec block. Not sure how much more compression it will give, but I know if you do the opposite your CR goes down.
