promaxx small block heads.

'These as cast heads utilize ultra-smooth new runner and chamber designs that produce "CNC'd type" flow numbers. '

CNC'd type numbers from what head, the OOTB EQ is 172cc and they claim 171cc. Maybe CNC'd 318 2 barrel heads....also of note, "assembled in america" . If they dont say where they are cast then its pretty much got to be China.

Price is pretty close to Edelbrocks which are cast in USA

My guess is people will buy them just because they are a $100 cheaper.
