Default Re: Getting all 3 Horse Power out of your GT-5 Sky? (tear down)

You could have a head specially made to go inside the cylinder 4mm, that way you don't ruin the jug if this doesn't work. This whole thing will raise the exhaust port, which lowers bottom end power and raises top end, if done right. The intake port timing will be affected as well, so you will have to carve out the bottom of it and lower the top with jb weld. Search that book of yours about piston port timing, and get a measurement tool for the degrees of rotation.
