Re: Machinist's advice sought
Maybe ask other 409 guys if they have installed hard intake seats with no issues. A buddy had a caddy head welded and had a seat cut in the welded material so that could be an option.

Re: Machinist's advice sought
That's why I'm afraid. Some went ok and some hit water. Not much meat there, I guess.

Re: Machinist's advice sought
Well, I took a close look at the stud. The crack only goes down to the pin hole. Surprisingly, (or maybe not since it was built as a race motor)the studs are threaded and there's no damage to the threads from it breaking off. I'm seriously thinking about just replacing the stud and living with the crack. I would drill it and re-pin it. The crack has no where to travel because it stops at the pin hole and it's only the top 1/8in. Am I crazy??
