hi all, got a set of BT aluminum heads that were drilled out to a big 1/2" size hole, as they were used on a cylinder set with 1/2" head bolts.
I want to use these heads on cylinders with 7/16 stock bolts, should i be concerned about the hole size difference, will the heads leak around the bolts??
building small sleeves will be hard, what about studs, any recommendations will be nice, as i am worried about head leaks around the bolt should i be??.
