are the guides in good shape? what brand of rockers? what springs? all things to consider.

The heads aren't really that great but they can be ported to make them a pretty good head.

idk the rocker brand, they are not colored rockers, just aluminum in color, he said it as triple rate roller springs, which dont matter, i have a spring compressor and will use my springs that match my cam and are new.

If the rockers are an unknown brand I'd offer him 200 and he can keep the rockers. It's a fair price for bare 220 cores, which is really all you're looking for. Tell him he can keep the springs too. If the guides and vj need work then you're looking at 300 bucks to get them to usable condition.

For that price, if they are clean, and the trunion spins smoothly on the rockers, swap your springs and run em.

I gave him the $300 for them, their in good shape with not much time on them, the guy bought them for a high power boat engine (fresh water) but put the boat back to stock and sold it then moved away for years, made some big bucks and now moved back and is sellin off old projects cheap and getting new ones. im sure dart iron eagles are probly much better but these gotta be close to 100hp gain over untouched 882 heads and stock rockers. next is to sell the performer intake and qjet for a rpm airgap and 750 edelbrock

I doubt that you will get any where near 100 horse power increase

I'm guessing with the rockers about 40-50. They'll add some much needed lift.

gota be more than 40-50hp,
these guys put a bunch of work into a set of 882 heads and stock dart iron eagle 180s still made 60-70hp more, so I think close to 100hp is possible from stock 882's and rockers, to these heads and 1.6 rollers.

100 HP gain from those heads & set of rockers is not very likely.If your 400 was built to hilt & the current heads were your choking point,maybe 60 HP.I wouldn't use an Airgap if you live in a cooler climate.

This is probably a bit big for your application but I have a new PRC-108 cam that I'm not going to use with a set of direct lube Howards lifters that I'd sell you at a big discount.

specs:
108 248 251 .531 .542 106 279 282

I installed it in a short block on the engine stand so it has lube on it but I never even put the lifters in the block, it'd be good with a larger converter, and the lifters are supposed to be some of the best street solid tappet lifters out there.

"30-30" cams are better suited to 350 and lower displacement, vintage road racing applications. I would guess something like a 270 Magnum solid lifter grind or similar. Of course, we don't know your transmission, rear axle, torque converter (if equipped) and the intended usage of whatever vehicle this is.
