In order to get a smooth power development and great usability, we will make sure all your components work in harmony. This will include setting the transfer and exhaust port duration to where it is desired for your build, enlargening your exhaust port window and cleaning out the space between port window and exhaust manifold.

If you just want to have porting work done without engine assembly, make sure to purchase a shipping label from us and send us your cases, your cylinder & your crankshaft.
