don't know, i didn't ask. i picked up another set of indy heads last week. my old indy heads that are setup for that small cam are going in the wifes motor with that small cam. i need to get my heads ported and order my new cam, springs and intake. pull the motor and trans and send the trans to CRT. it'll be a few months before i'm on the road again.
i over heated my boat two weeks ago so i'm fixing that first. i'm going to pull the head cover off this weekend and pray i don't brake any bolts. (125 outboard)
