Is there a reason to go with one over the other? besides possible fit issues.
Slant Head vs Straight Head

my beach cruiser has a 66CC straight head and my mountain bike has a 49CC slant head. the slant head has more torque and is actually more responsive on the throttle than my 66CC straight head. people that have ridden both of my bikes can't believe the slant head is only a 49CC!
My slant head showed up TODAY!!! Good service.
Unfortunately I'm busy as heck - maybe Friday I'll throw it on. I can tell the mating surface isn't perfect.

Hi Pablo
Does the slant head have a squish band?
They never show the bottom of the head in pics.
The Raw / PK 66 cc / "80" does not and it is a very badly designed combustion chamber.
The Grubee 66 cc does have a squish band and the motor is way
stronger than PK's right out of the box.
It has a squish band.
I'm not particular impressed by the cut out near the plug recess. Not sure how the sharp edges will effect combustion. The fins are relatively small as well.

small fins but you get 1 more fin than the stardard fin. I have a slant head and the power is better.
I agree better power, and better power much sooner. (I didn't count the fins!)

HI,
Sharp edges in the combustion chamber can cause hot spots and detonation of fuel at the "wrong" time....Best to smooth out any rough edges in the combustion chamber.
