Thank you all for the replies. To shed a little light we are building a 66 383 for NHRA competition, yes I understand the 516 are a decent head, but we have to meet NHRA specific guidelines, and they allow us to use the 915 for 66-67 combos, and they allow the 915’s intake runner to be 23cc...
NHRA class rule for the engine combo is that it must have OE valve size. NHRA allows us to use the 915 on 66-67 383 in place of the 516, but must retain 2.08/1.60 valve.
Looking for a pair of small valve (2.08/1.60) 915 head bare castings for a project. I am in eastern Canada, so you must be willing to ship at least to my shipping address in Maine if not all the way. Not looking for rebuilt heads, just bare castings. Thank you.
