So one of my seats is crumbling and I was gonna send the head off to Millenium Tech to get new seats installed (possibly new valve guides) and a cnc valve job but I noticed that Cylinder works came out with a complete head that has new cam caps, new C630 (nickel/aluminum/bronze) valve seats and valve guides and a CNC valve seat job for $360. Seems like a sweet deal and then I can sell my stock head and make at least a couple hundred back but on the other hand I like the idea of letting the pro's cut the valve seats and they will have my valves so they can vacuum test them and make sure it is getting a good seal. I do have a vacuum tester myself or I could do the liquid trick but if it's not making a good seal I'm sure they would do a way better job then I could at correcting the issue and that way I will know I'm getting a head back that is ready to bolt up and ride. Here's a video on the CRF head but mine is a kx250f however you should get an idea of the decent quality. Also below are the details of the head from their Ad.
Any one that has tried these that could give real life feedback would be great but I'll take other opinions on which way I should go as well cause I'm really torn. Thanks

if I had to redo I would have stuck to oem titanium on both intake and exhaust sides. I have a video of it on youtube, heres's the link https://youtu.be/h6kvAmh7J1Y
