Small Block Head Flow Chart

Screws numbers aren’t really very viewable on my phone, so I tightened up the columns:

CNC IndyBrocks out of box 2.055 1.6 valves, Indy's exh #s are without a pipe, mine are with a pipe

column 1 Indy's advertised #s
column 2 actual out of box #s
column 3 fixed valve job and better Ferrea valves
