Rules here say we can use the World 4360 s/r 76cc head, stock size valves. I've heard they were good, heard they were junk and I've heard they can be good if you do a bunch of work to them. So I've got my choice, buy some 441 heads or world heads. If I buy the world heads I was not planning on doing additional machine work. So does anyone know if a "out of the box" world is better than or worse than a 441. Thanks everyone in advance!

I would like to know also. I do know the 3932441 head has 152 cfm intake flow and exhaust 93.2 cfm.( WWW.thedirtforum.com/castings.htm.) The only spec I could find on the 043600 was 76 cc chambers and 171cc intake runners.
We use the 043600 but don't have anything to compare it to.
World products phone # is 631-981-1918
good luck
More info to confuse you. I guess it depends on the cam. check this site out.
