which kit to go with

[quads14589]

im debating on getting a 426 kit or a 416 kit for my 400. i want my 400 to be able to keep up with the 450's on the track. i kno with the 426 you have to bore out the walls in the motor but with the 416 you dont have to.. im also going to get hot cams stage 2 put in but im kinda worried about the price if i have to get my motor brought to the honda dealership to get it bored out and to put the new top end put on so which would you guys do to have your 400 keep up the the 450's on the track even tho i wont be racing just leisure(sp) track riding and trail riding.

i would go with the 416 it is the cheapest and then you can always bore up you can't bore down! and the stage 2 should work well for the track i would consiter getting my head port and polished to and a hd timing chain and hd head studs
