UPDATE: **SOLD** Was $150.
Paul spotted this hi-compression head designed for high altitude engines. As I understand it, the “High Altitude” option had a higher compression ratio of 7.4:1, compared with the stock ratio of 6.9:1.
“Hi compression Hi altitude Head for the tough Hurricane 4 motor . It is complete with valve train and has been freshly resurfaced . If you spend time up on the rim or any other place where altitude could be an issue for full performance then this is the answer for you .
Thank you for looking . I also have other 134 cu in Hurricane 4 parts available upon request”
