Nope, no tools for me.
Just looking for someone that's good at what they do, and their method kind of caught my eye. I thought about doing the work myself, but just decided it would be easier to pay someone to do it.
Part of what makes the Extrudehone process expensive is the restriction plates that need to be engineered and bolted into place where the putty exits. Unless you have something common like a small-block Chevy, they have to design and make a plate to fit your application.
It is a cool process though. It has the ability to enlarge and "polish" ports and runners where regular hog tools can't reach. I think this process was originally designed for the jet engine industry.
their stuff works!!!
a guy I knew had his head and manifold done on a LS/VTEC, and was running 12.0 all motor in a gutted 92 Civic HB (his motor was built with 12.5:1 compression and some mean cams too but he said the high end impoved greatly when he had the head and manifold done)
