But i am not impressed with any of their work on this motor. But the motor was rebuilt 3 yrs ago then sat till i purchased it. So move on and fix it right.
Dont spend a dime repairing those heads. There’s another 100hp in there with modern heads and compression. Assuming you’ve got a good exhaust system. What is your exhaust setup?

gaffrig headers dry to the tip. My mechanic caught the head while test firing and prior to dropping the motors in so i had him replace it at that time. Would have loved to put better heads on at that time. But after replacing everything in the bilge i was already way over budget and out of money. Like any good boater lol. So the goal is to work with what i have but replace the cam and valve train.

its a thread hole for the extra head studs that get used if the block has the bosses.

I ran the extra bolts with the Big M block and multiple sets of heads, never saw them come through the intake port. Maybe I was just lucky, seems like a great place for a vacuum leak.

It needs to or should be plugged from the bottom side when not used.

The Brodix heads that I used were tapped for studs, the holes never came all the way through. I believe the stud kit came with the Big M blocks. Different manufacturers do things differently I suppose.
