10 degree valve locks for the stock valves?

[turbodave]

When I say stock valves, I mean oversize but otherwise stock...

I can get the 10-deg locks from www.realsteel.co.uk for £45 but wondering if anyone knows of a US-based part number for a 10-deg keeper that works with the stock valve stem; maybe it is a standard square-cut lock, but I want to be sure for obvious reasons. I've never understood why the groove in the stock Rover V8 valve is so long compared to others I've seen....

No point in using 10 degree lock with lower spring pressures.  10 degree locks are meant for high spring pressures.

Of course, they also require the appropriate valve spring retainers.

I'm going to buy new retainers to suit beehive springs, so that's irrelevant. I guess I'll just buy them and hopefully they will come with a US based part number.

Dave, have you look at TA Performance ? They list 10 degree locks, part number TA V1434C.

Re. beehives: I assume that you are assembling Rover heads ? Are there currently beehives available that fit Rover heads ? Couple of years ago I tried to find them but had no luck. Even uprated normal springs are hard to find. Rover springs are relatively short, one option would be longer stem valves but that creates other issues.
