Excellent Kit!! Went on so easy they almost installed themselves. My '93 FXDL really needed this! 80 CID to 85 CID really made the old girl come alive again. HIGHLY RECOMMENDED BY ME!!!!

Kit does not work with Screaming Eagle heads.

The parts were as ordered The only thing I had to do was size the rings. The fins on the push rod side are not all highlighted like the stock cylinders.

So far it has been great, Allready have about 4 k on rebuild and the extra power is nice. Definetly recommend it for any 80 ci motor

Already have this kit on my 97 Dyna so when the top end needed done on my 97 Road king no question. For the price of the kit compared to new Stock Cylinders, Pistons n Rings, this kit wins hands down and if broken in correctly will take a good beating for quite some time, my dyna is still taking it ..
