I have a 1999 Road King with a 103" engine. I am using the Harley cylinders and flat top pistons. Along with this I am using the Screamin' Eagle Harley Kompressor heads, Andrews TW50 cam, Vance & Hines 2 into 1 Pro Pipe and a Mikuni carb. I was looking at the Andrews 54 cam. Harley says with these heads the compression is 10:5-1. Any thoughts?
