How detailed are needing?
Billet rod (10 or 20 over)
Black mamba cam (not the junior)
Flattop piston from Honda
Billet flywheel from ARC (or pvl type)
Bored carb or 22 mikuni
Candy cane header with muffler
Upgraded valve train (stainless valves and pushrods)
26lb springs
14cc head
Pull the gov out
This should get you close to 8000 RPMs.
I agree with this.
However the Honda 68mm Flat top will not fit the new loncin 70mm bore.
ARC racing has some pistons that are flat and fit this bore with a stock wrist pin.
You do well keeping the compression under 11:1 for a street aplication.
I like to have a tight quench on these engines with closed chamber heads.
I prefered the 14 for many years because although it was restrictive it made great torque and let you run high compression with pump gas.
Things have changed and these new larger engines would be better suited in my opinion with the 18cc milled if desired but I think as built they will be fine for a 10.5:1 compression.
So too get all that I would run the rod that gets you closest to zero deck and run the right thickness of gasket for about .030 clearence.
I would not use ratio rockers because you wanted a big valve head.
With the momba grind I do not think you need more lift.
