Power Bee 820 High Compression Head!

I took the best of the Horstman Head and the USMP Copperhead Racing head and made some improvements. It has the Hemi style combustion chamber, and is machined to sit lower into the cylinder, in order to create more compression and more power.

I added a little extra cooling fin area above the spark plug, when compared to the Copperhead Racing Head. I aslo added a compression release area for people who want to try to use an automatic rewind (recoil) startr.

The head fits all 820 cylinders (WB, Chrysler, US820, or modern). Unfortunately no 610’s.

The price will be $180 for the head, or $200 with gaskets measured to give you a .022” squish gap on a stock 820 cylinder and stock 1.625” stroke. PM directly to purchase or pre-order for the next batch. You can also subscribe to the blog and newsletter on the website to stay up to date.

(Some cylinders have been modified or machined slightly. Fine tuning with copper shims may be required if your cylinder has been decked)
