Valve relief: proper or poor

[Guest]

I bought a bunch of GS1000 engine parts, and I'm trying to figure out if this valve relief job is god awful or par for the course. Chambers were polished. It's an S-3 head (not sure if that matters) intake ports are sized for vm26 carbs. Is this garbage or will it run?

The first four pictures are of the area where the SHIM BUCKET lives, not the valves.

Can't imagine why that area has been ground, there is NO air flow through there.

In the last picture, it appears that there has been some minor grinding outside of the seats, but can't tell for sure.

You should, however, at least chase the threads on the spark plug holes to clean them out.

Those areas have been trimmed to clear cam lobes with higher than standard lift....some nicely, some not...I've seen it done better, and seen worse too.

How nicely doesn't really matter as long as the lifter bores are still clean and straight.

Steve, sorry, the correct title should be Cam Lobe Relief.

Greg, thanks for the thoughts. I'll probably try to clean the reliefs and check the bores if I decide to use this. Glad to know it's not ruined by a heavy hand.

Makes more sense that way.
