Why are exhaust pipes leaking on my Shovelhead?
Due to there being only a single bolt to hold the exhaust flange, most Shovelhead riders have experienced the annoying exhaust leaks where the pipes connect to the heads. These leaks result in exhaust blow collecting on pipes, frames, and other places, as well as a muddled exhaust tone.
How to build a high performance HD Shovelhead engine?
Use main fuel nozzle per figure 0. If the float bowl has been for accelerator pump bypass, the bypass must be closed off. Exhaust pipes and intake manifold will have to be modified as a result of the lower cylinder heads. The cylinder head bolts may have to be shortened by 1/8″ to prevent them from bottoming.

Do you need hydraulic lifters on a Shovelhead bike?
In fact, if you run an Andrews 3 grind or an S&S 514 on up (for example) you MUST use solid lifters. If you use your bike on the street or for touring you will want the reliability and decreased maintenance requirements of an hydraulic lifter set. Shovelhead riders may be interested in upgrading to Jims Powerglide tappet blocks.
