ISO: M30B35 Head

[Aviveiros27]

Looking for an m30b35 head late model for my 89. I did a headgasket replacement but never checked for warping. I believe this to be my issue to low power and hot temps. If anyone has anything: performance head, or just a nice flat verified head, please let me know.

I have a few B34 heads, I'll keep my eyes open for a B35,

Why don't you have the head surfaced and do a valve job at the same time. It is the right way to go about it. Do it once and do it right

I don't want to go through the process again to find out it might be cracked or beyond spec. I'd rather just buy a verified one.

I think Bert's suggestion has merit. I don't know how you would find a "Verified" head.
Even if that was possible, you would be smart to have it checked out.
I'm with Bert, have a machine shop check yours out then you'll
know for sure.

If you are pulling the head, its best to just send it to a machine shop to have it checked. You should be able to have the head resurfaced and a valve job including a tank clean and pressure check for around $400 - $500. If the head is cracked, the shop will likely give you a time/materials bill that would be considerably less. Then you can continue the search for a good head.
