Billa, if you watch ebay or better yet local swaps a set can be had for $200, and most of these used heads are OK out of the box (new engines, low miles, good used heads) and can be bolted on and run, so $200 is way below $500, no? I have a set of 062's on my 99 tahoe with over 100k and I'd bolt them onto any 350 and run em, they are like new, no smoke, blowby, dilluted oil, nothing!! New late model engines with fuel inj last way longer than our old 350's, look at carcraft's junkyard jewels articles, they buy late model efi engines and rering and pound the dog out of them. Find wrecked vortec trucks, cause you know they were running when wrecked and you'll get a good set of used heads that are ready to bolt on and use, and you're worried instruct your machine shop to disassemble and inspect to insure no problems!
