Look up Driveline Performance we make banshee cylinders and can help you figure out what topend might best suit you.

I replied in your other thread but the porting looks pretty clean over all. The boyesen or boost ports are awfully small. It's really a touchy area on most cylinders and if you dont do alot of them, breaking through to a stud hole or the outside of a cylinder can happen quick. The durations of the other ports have more to do with the overall performance of the cylinder than boyesen ports. Here's some pics of some cylinders I did lately.

You could connect those dots. They probably didn't small enough carbide burrs to go in those holes. I start these with a .250" hole and 3/16 burr and end up 3/8.

Could someone move this to haus of projects? Still new here and realized that's probably where I should have put this. Thanks

Here's a kx500 cylinder I'm working on today for a drag bike.

Mobil 1 5w30 full synthetic

Loctite 620 is some badass stuff. Like the others said it's the proper stuff to use on cylindrical bearing journals etc.

Those actually like the only 2 pictures relevant on my phone that are under 650kb

How are you resizing pictures and posting them. I'm used to tapatalk forums.
