I resurface the heads myself and H6s have always had more high and low spots than H4s. The hardest parts to get right are all the timing cover orings. check valve clearance. I grind the shims to adjust clearance and put the ground side facing down so it doesn’t matter. No way I’m playing that shim swap measurement song and dance. Theres no big gotchas. It’s like an H4 but larger, heavier, more parts and therefore more cumbersome all around. The upper forward corners of the timing cover/valve cover interface have a funny bracket that kind of “goes one way” to get off and back on but it’s easy once you look at it and it’s a really small minor part. You likely wouldn’t have noticed even.

The intake/exhaust and those other loose ends should be in the Fel-Pro kit. Hope so, anyway, now that I see how many stupid O-rings are on the back of the timing cover...
