I bought a camplate and rollers from him a while back. I checked hardness of the camplate vs the stock one and dimensions of the cam and it was all within a couple thou, and it was a couple points higher in hardness, all well within any sort of tolerance. The rollers I wasn't as pleased with since they're a 3 piece instead of the 2 piece I pulled out, which would allow for stacked tolerances, but Seattle Injector didn't pull them out when my pump was rebuilt, so I'm not worried.I'd order from him again.
Can't speak for the heads myself, but I ordered door handles; boost, EGT, oil temp n pressure gauges for my Mkii... Surprisingly the handles have held up really well, even through our winter, and gauges got the approval of my mentors and friends, not to mention the handles are one of a kind here, heheheThe kicker is he sent my stuff to Canada via family headed to Eastern Canada, and delivered to me via Canada Post, a rare display of courtesy in my eyes
