    185 was a low performance head from the mid 70s. I had a 350 core that had some way back when. The heads are worthless, 1.72" intakes and 76 cc chambers. They were on a 010 block just like this one.

    As far as factory castings go the 186 is a good 64 cc head with accessory holes used on HP 302/350, 69/70.

    If it's '186' (and NOT 185- which I'm not familiar with either).. It's a GOOD head, as good as factory heads of the time can be. They were machined for either 1.94" or 2.02" intake valves (depending on the engine it was to be installed on). 1.94" went on 300 hp 327 and 295-300hp 350's, and the 2.02 went on 350-370 hp 350's, and Z28 302 ci engines. Need the date from the engine block. Don't change anything on the engine until we get it figured out. Get the date of the heads also (under the valve covers)... your engine *might* have some value there (to some people) if it turns out to be a HP or SHP engine (even if it's a warranty engine). Many people are restoring late 60's Camaros, Novas, Chevelles, etc.. and if they are missing their original engine, having a date appropriate correct CE engine is their next best choice!

    Please take some overall photos of the engine, intake manifold, carburetor, etc... including exhaust manifolds, and heads under the valve covers (and another better photo of the back of the engine block which captures the cast date!).
