I have been planning a ballanced build but I am waiting on money and time.

My plan is 10:1 CR up from 8:1

Knock prevention includes
Ceramic thermal coatings particularly on the exhaust port and valve.
High flow water pump.
cleaning up the water jacket for better flow.
Combustion chamber smoothing
Oil jet piston cooling
Cold air intake
Custom program with an aftermarket ECM
long tube headers
High flow exhaust, mufler, CAT.

More perfomane minded mods
Cleaning up the ports for better flow velocity

Other efficiency mods depending on money
Roller rockers
Roller cam ($1600 for my engine)
Ceramic coated bearings (more for durability)

Aluminum heads will help (mine are Iron), but even then I wouldn't suggest going past 12:1 with a low RPM cam
