ok ... i kicked my lazy *** and completely removed the engine from the frame...

drained the oil and cracked open the side cover (1'st time ever in this engine's life!) it looks absolutely lovely inside and i think i felt in love with my honda... so now i wamt to put reliability upgrades in it so it will hold up better the abuse....
here is my list:
ARC Billet Rod With Bearings
ARC Racing Billet Flywheel
Valve Spring, 18lb.
Flat Top Piston
Ring Set, Standard Bore
Wrist Pin, GX160/200
Wrist Pin Clips
total 215$
question is... would i need a standard bore piston or a + 0.10 , and file to fit ring kit or a std bore???
and is there missing things? like could i keep the stock piston or the flat head is recommended?
edit: wee got myself a set of feeler gauges and a torque wrench to properly build my engine... I'M GONNA CREATE A MONSTER!!! lol well not like tyler's rhino but oh well mine will be turbo
