This one for the AXYS isn't higher compression, it's actually slightly lower compression. The Horsepower gain is from the dome design with a hemi style pocket and adjusted squishband.
We also have the updated larger and cooler thermostat version so you can update your 2015-2017 model to the 2018-19 version. Even better cooling and more stable horsepower.
ANOTHER BENEFIT OUR BILLET HEAD HAS OVER STOCK AND OTHER BILLET HEADS, IS THAT OURS USES O RINGS TO SEAL THE HEAD BOLTS INSTEAD OF USING SILICONE.
