Pinto head ports are only 38mm dia....which is big enough for monster power!

who said anything about a pinto, lol
race heads arn't 38mm inlets are they? i know for sure they use 45.5/46mm inlets cuz i've got them, arn't the inlets opened up so
that you have 45mm running all the way threw to the valve

Race Inlet valves are 44.5mm od. Stds are ~42mm IIRC
Ports themselves are nowhere near that diameter though.
The ports are virtually always retained at 38mm diameter on all race heads I have seen. The optimum valve size for that port is still larger than can
be fitted to a pinto head (~47.5mm IIRC)
Hence why even most race engines only run 45 or 48 DCOE carbs with max 38mm chokes fitted. Anyone fitting 50's does it purely for poser value
and no real performance gain
