We designed and built this Billet Head in 2008 (1st year of the new CFI Liberty
Engine but was not able to make more than 4HP over the 14:1 Polaris Stock Head's
In 2009 to Present, Polaris lowered the
compression ratio to 12.5:1 with a less effective design.
So, since Polaris has went back to the old "No Power" Design chamber. We have
decided to re-release our Torque-Line Billet 800 CFI Head to the public.
This head will gains some much need cooling and add about some serious on top end,
as well as, mid range power increase..
We have some INDEPENDENT DYNO runs on a
2012 RMk ASSAULT comparing the STOCK Polaris head to the RK Tek Patented Head
NOTE: These Dyno runs are comparing the SAME compression ratio.. These
dyno runs show a SOLID 6-8HP INCREASE throughout the ENTIRE RPM range with a
HUGE increase in Over-Rev... Again, this is comparing the SAME compression
With the higher elevation, where one can run higher compression, the
power increase will be MUCH greater.
We just wanted to show you that
compression is NOT was is allow the increase in power but, rather the RK Tek
Patented Chamber Design
See for yourself.

BELOW RK TEK HEAD AT SEA LEVEL
WITH STOCK COMPRESSION RATIO
This head is especially beneficial when making a big bore engine or in a turbo application!
Cost of this Patented Billet Head: $465.00
NEW for 2012 and Beyond:
Since the bean counters at Polaris are
SEARCHING for ways to make your warranty VOID via asking the dealers to perform
a visual inspection on EVERY sled that comes into the shop...
RK Tek has decided to do a little
"cheating" of their own.
RK Tek PIONEERED the first "Cheater Heads"
WAAAAY back in 1999. We actually use your OEM stock
head and machine it to accept our Billet Head Inserts. This way,
the head is totally stock appearing, YET, has all the benefits of our Patented
Combustion Chamber Design.
So, you get RK Tek's Patented Combustion
Chamber installed in your OEM Head Shell! What can be better than that?
Now, the Dealer can "officially" inform Polaris that your engine has the STOCK
Now, you can have the "#1 Bang for your $$"
RKT Pro Drop In Kit
OR the Monster Power
858 Big Bore Kit installed and NOBODY
would be the wiser!!
