RK Tek Head for 06 M7 $250

[hcr_1]

This head was only used for maybe 300 miles last year. The domes were designed to run on pump gas at 8-10,000 ft. I believe they are 13:1. It is the gold colored torque line head by RK Tek.

92 or 87 octane at 8000 ?

At those elevations I would think more like 15.0 - 1... mine are 13.6-1 for 3000' and up....

I was told it would work with 92 octane. I'm not real sure on the compression ratio.
