engine opinions
i think my engine might need some help and i am thinking over my options.
i have some Q's though
is the iron head 86 1pc rear seal or 2 pc?
is it cost effective to rebuild the engine, or is it worth it to buy a zz4?
i would do all tear down/assembly myself if i went the rebuild route. and have the machine work done?
the engine has been overheated (badly)

1.All 86 are 1-piece
2.Its up to you, the ZZ4 is a good replacement, but it wont make the rated power once you put the TPI intake on it, and it will want a chip made for it. It'll still make more power than the 86's engine though.
Start pricing your parts up and see which way will end up best.

Crate motors can be great, but EXPENSIVE. If you have the time and a good machine shop near by. It will cost a lot less to do it yourself. I dont have a lot of faith in the machine shops around here, so I do as much as possible to avoid them. Like, it may be better to buy new heads than have old ones fixed.
