360 to 408

BUDGET!! WE sell them for 1295.00 with 8mm Ferrea 6000 series valves, all machine work done, 2.02x1.60 with the bowls cleaned after the valve job, Comp beehive springs for up to .600 lift!

There is no QUALITY aluminum head that can compete with these heads and they flow 268cfm at .500 lift on my bench and 272 at .550!

do you have the flow numbers for them? and is this with work or no work?
