I just order some stainless steel valves 1/64 over for a stem diameter of .327. They are going in an OHVC with cast iron for guides. How much clearance do you need?

You did good. That will work.

Ok I didn't read that right. Use a reamer for the .015" oversize from the vendors.

Are these standard type model T valves? In the block? Or "over-head Valve" valves in the head? Are you referring to valve stem to lifter clearance? Or push-rod clearance? Cam in head or rocker? They are all different.
I am SO confused! Been a difficult week.
If the standard type but .015 oversize stem valves, yes, Mike B is right. The best thing is to just order the .015 oversize reamer to fit the valves in the block.
Drive carefully, and enjoy, W2

Mr Steele has a Rajo in his cool Detour Deluxe pickup. It's such an inspirational vehicle I've planned to build a copy of it out of my pile of extra parts - no Rajo though. Only external difference will be tractor seats instead of camping chairs :-)

And the question - I also think the reamer for 1:st oversize stems from the vendors will work fine: http://www.modeltford.com/item/3052BR.aspx
