Holy smokes!!! Had no idea old dinos like these fetched that kind of scarole. Good luck with the sale
These definitely need some work. Looks like they were cut for valve seat inserts , probably due to seat recession. When the rings are installed they will be over lapping so extra care has to be done to retain tension so they don't loosen up. A good machine shop familiar with this is necessary.
Don't know , I haven't installed seats in a while. Looks like some repairs were made too which need to be checked I'm not trying to disparage these heads, they aren't mine and I hope I'm not out of line for the seller. Certainly dont want to nitpick and jeopardize a sale.Only offering an observation.
Installing seats isn't too big of a deal. These are without question worth the asking price and fixing.
My iron Stage 2 had to be welded because some tried to do just this, So it appears when cutting in the seat they broke through to the water passage & tried to braze weld. From what I remember there is not a lot of material to put seats in these heads with out cutting into water & having them seal without leaking. These will need to be cast iron welded & remachined. lots of money.
I run the pressure test table where I work..diesel heads , LS, 409, Whatever. Seal up the openings and take whole shebang up to 25-30 psi Then lower into water You'll know right away. . Pinholes , porosity. That's prevelent in repairs .Thanks for the pictures.
The replacement seats need to much more shallow with Buick heads vs the other makes. This isn't a big deal, just as long as the machinist knows this before hand. I would start with a pressure test before installing the new seats and go from there.
