Hi all
Anyone know what the valve clearance is?
I am not ready for it yet just getting facts together.

Many thanks
Graham

I would say as long as it has some clearance then it will be fine. It's not like it's going to run for extended periods where everything gets thoroughly hot, expands and clearances reduce. If you make it to large you're reducing your cam lift and duration, which won't affect it all that much anyway - again it's not like full size where we're chasing maximum power. So I'd just set them so it has a little clearance by feel and call that good enough.

Hi All
Do the valve cages sit flush with the head cylinder cut out? or are they .017 below.
Depth of recess in head .397 length of cage .38
They do not look right when .017 below and would presumably restrict gas flow as valve head would only just fit in, waiting loctiting so answer would be appreciated.

They should be .017 below. When the valve is installed it will be flush with the surface or real close to flush. There is plenty of lift and duration in the cam to get the cylinder filled up.
