A-block head milling
the only way to know wether you'll be a-ok on the intake lining up is to 1st set the heads and intake on the block [with gaskets] and see if they line up NOW before any milling, if it's boarder line then you better mill .010 off of each intake face of the head.
and just use some black RTV on the front and rear rail, skip the cork end seals.
