Not much else to report. I haven't been able to mess with them much.

Over all valve heights are pretty close. Some are branded different then others and have slightly differing lenghts. I assume those were replaced at a refreshen with whatever the shop is using that week. The combination of the slightly different brands, nominal over all lenghts, some were likely ground on the stem, and whatever seat heights and 3 bent valves seem to be stacking up to the differences.
Im sending it the shop for seat and guides as I don't have the tools for that. Does someone need some work to do?
I was just being humorous earlier, but now it seems that maybe it was Clem and Cletus at "Billy Bubba's Rase and Micheen Survise" that just "freshen'd" them.....

I like the southeast but whoa! Kinda feels like they were digging into the couch cushions looking for stuff to use. I forgot to mention a spring locator was missing altogether. The others were .620 on a .560 guide. That’s gonna be fine right?...for a few minutes. This kinda thing just goes to show ya got to check it. New, used, broke or beat up or rebuilt, ya gotta check it. No matter what the back story is supposed to be.

Verified junky lol
Machine shop has em now for guides and seats.
They won’t let me do my own spring set up. They prefer to do the springs and everything so they know for sure when it leaves it’s ready. I’m alright with that I guess. I like doing my own work cause I’m just gonna take them apart and check it again anyway. They just don’t like it when dummies blame them for their own mistakes when a keeper isn’t seated or a seal isn’t just right or it’s coil bound or whatever. They have my cam card from Mike Jones, my springs, retainers, locks and locators. No extra charge to set em up either. The up side is they really like the port work and the decks are flat and the spring pockets are good. Seat height is within tolerance so they will match up the valves and get the stems right. So for $1300 all in, it’ll be a nice set up on my little engine.

Iíll finish up this with an update.
We ended up going to a bigger valve because the seat heights were all over the place with previous valve jobs. I kinda get the impression that some valves were repaired after previous blow ups but only the effected holes so several quick jobs later and ya got a mess. Worse than we thought previously. In order to get the seat heights the same we went to a Ferrea 2.100/1.600 valve that weigh 115/90 grams. New ISKY 1.55od springs with 140lbs on the seat and 360lbs open. Titanium retainers that weigh 14grams and super locks at 6 grams a pair. The cam is a custom grind FT with .590 lift using a 1.8 shaft rocker. Theyíll be a really nice set of heads for the money and last good long time even if the price tag was higher than expected.
