Well, NGK makes plugs that are 5-6 steps colder than what we use stock.

R5671A, non projected tip or R5672A projected tip.

R5671A up #10 heat range, I was using #7's for 85 shot, #8's for 100 shot.

They were suggested by Tom Payn.......the non projected tip transfers heat quicker, less likely to melt.

for every 100 hp over stock you need 1 step colder (per ngk),but not to exceed 6 steps colder than stock.

500 hp is 400 over stock so that's 4 steps colder.

You need colder plugs because if the plugs are too hot the can actually ignite the fuel before you want to causing preignition which bad news bears.

honda cranks can handle well over 1000 HP. unles your stroking the engine, you do not need a crank. honda makes the best in the world.
