Junkyard 5.9 for my 72 Van

Just a FYI, it is recommended to not mess with the ports on CH318A heads except for a port match as they flow well already.
230 cfm if I remember correctly.
I’m running 96 5.9 with the CH318B heads and small port Edelbrock dual plane with a Holley 770 Street Avenger.
Mild cam and Hughes springs, retainers and locks.
Stock rockers have been fine for 5+ years in my daily driver. :D

Thanks Trail Beast! I appreciate hearing that. Just port matching if I can get top it :)
Your car looks great!
