sunk valves, stem height problem

Hi there again thanks for the comments so i finally got new exhaust valve inserts installed... i measured the springs installed height and they are ALL DIFFERENT but they are withins soecifications so good enough... Off course this wasnt for free the machinist thought i told him to replace ALL the seats so he cut out one intake seat ( i wasnt really surprised at this point) so i have 9 new seats... So now that i know the engine is not going to selfdestruct in five minutes I hope i can run this heads for 20k miles or so meanwhile ill look for an used pair in good condition.

When picked up my heads there was a pair of chevrolet 350 heads in The machine shop, It was the first time i saw a pair of those unassembled, I was very surprised by the obvious superior quality of the chevrolet cylinder heads here are a few things i noticed:

Bigger valves
Thinner stems
Bigger ports
Integral seats ( both intake and exhaust) vs integral int exh insert in the mopar
Nicer cast less flaws
Stud mounted rocker arms and all the otjer things everybody knows

Im not a fan of any car manufacturer i love all engines the whining hondas, the mazda rotary, the diesels etc. I am fascinated with all off them, i just preffer old V8's all that being said after taking a look at those chevy heads i was very dissapointed off my mopar cylinder heads i guess thats the reason why small.block chevrolets are so horribly popular in the performance world.
