the springs and timing key are the same, some of the gx670 headers will fit and some won't. honda had two different series of gx engines, Randy from Wicked Carts has a header that i know will fit your 20hp if its not the industrial series, and its on sale

the easiest way is to look how the intake manifold mounts, if it mounts on the side of the heads, its a standard engine. if the intake mounts to the heads in the valley, its the industrial.

thanks NUBS i was going to say you have used one of my headers....

there should be a model and serial number plate somewhere on the motor those numbers would tell you all the info....
