A few questions for ya.. is this a street car..
(assuming its a street/strip set up) you can
put the timing back to give you more clearance..
what head gaskets thickness.. can you give the
open/close specs on the can(this will help tell
you if you can move the cam.. I just cut a set
of pistons yesterday to lower my compression..
you can also cut the valve pockets to help if you
dont want to move the cam.. ( I always use a zero
lash to get my setting.. just saying)
