Yup……casting numbers 53005714. Interesting that they are 1.88 intake and 1.60 exhaust tho! Cool, but too small of runners for my 340!

Measure the valve seats and report back.

Could be one of the 318 four barrel heads if it has 1.88/1.60 valves. Some casting numbers for those are listed as being used for both 318 & 360 4 barrel engines.

Those would then be 360 heads.

Yes, casting numbers I have seen on stock 318 four barrels were usually 360 smog heads.
