360-1 Indy intake

Nice heads PB-racer!

I thought I read somewhere that the RADIUSED seats are BEST for flow, but BAD for fuel Vaporisation?

Swings and roundabouts but still, anything in the 300cfm's is COOLIO!!!:):(

Seen those valves before with TINY trapdoors on the lower edge!
Lets stuff through and not back again...:thankyou:
