1970 Chevy "186" casting 2.02 x 1.60 heads
For Sale 1970 Chevy <span style="font-weight: bold">3927186</span> Heads casting dates <span style="font-weight: bold">B90</span> on both heads. These were a matching set of heads pulled of a running motor 10 years ago. I had them dissembled and hot tanked then the NAPA machine shop closed before they ever got assembled 10 years ago. I sold my car they were for. I have no need for them.
I took them to a machine shop last week to have them inspected and checked for cracks. They passed magnaflux with no cracks. I did this so someone will know they were good heads. The heads will need assembled and setup to your cam specifications $550 Call 937-321-0655

They don't look to have ever been cut to unshroud the intake valve.

Re: 1970 Chevy "186" casting 2.02 x 1.60 heads
That's because they are 1.94 intake valve heads - at least originally. These are the perfect starting point for converting to full Z28 heads, fresh material for valves, seats, converting to screw in rocker studs and unshrouding the valve area. Good dates as well!

Re: 1970 Chevy "186" casting 2.02 x 1.60 heads
Thanks for the feedback on the heads.
They may have started off as 1.94 heads not sure. The 2.02 intake and 1.6 ex valves shown are what the machine shop removed. The valves and springs are in great shape I am asking $550 but need money for other project. Make an offer.
