The heads I took off of the motor was shaved to almost the spark plug holes but I don't have ant clue on the CC

take them to machine shop and have the cc volume checked but i think there way to low

64cc head should get ya 10:1 er so...

my world products 64's have plenty of room from the deck of the head to the plug hole

Kind of a SWAG but it sounds like somebody with a milling machine had a bad idea and made scrap out of those heads . .

But Hotrod's probably right. Go have them measured . .

They could have been from a past 'case of beer' bench racing in a machine shop experiment :shock: 8) 8) :lol: :lol: :oops: :roll:

there had to be at least a case of beer in the man behind the cnc machine :shock:

Sounds good I will take them to a machine shop and see what CC they are, another question this is a roller motor and the #3 & #5 lifters are different than the rest they are rollers but instead of the bar assembly that connects at the top of the two lifters these have like a middle brace between the two lifters and with springs in them, I'm scratching my head on this.

hmmm idk why that would be it seem as if the guy just threw this thing together with spare parts

X2 . . . . . A "Handy Grenade" . . Whatever he had handy, he built a grenade out of. . .

Got me thinking the same thing

I really appreciate all you guys input on this motor it sure has help me make a decision
