Arctic Cat ATV/UTV Head Porting

We offer 3 Stages of head porting or head modifications for Arctic Cat ATV/UTV models with the 550/650/700 H1 engines. We offer these different stages to cover everyone from the everyday rider that wants to slightly modify their head for some extra power, to the hardcore racer that wants to fully modify their head to it's highest potential. So if you’re just looking to beat your buddy down the trails or have a full race ready set-up, we can give you what you are looking for!

STAGE 1: Head porting plus intake & exhaust guide modifications if neccessary. Includes new valve seals and H5 Valve Springs (a $118.75 value).

STAGE 2: All Stage 1 modifications plus a 3 angle valve job.

STAGE 3: All Stage 2 modifications plus larger intake valves.


All Prices are on exchange basis and you will need to send us a GOOD core head for exchange. You will be charged for the stock head core when we ship you ported head unless you send us your head in advance. We have completed units on the shelf for outright sale as well. Please see the options above for the current pricing.

NOTE: Stage 2 or higher is suggested on all machines.
