Yella Terra makes 1.7 ratio rockers?

Indeed they do:

I haven't had any issues but I did take 50thou off the top off the valves to offset the extra lift. Maybe that is robbing me of lift now that I know there's enough space in there but I thought it prudent at the time.

Changing the overall length of a valve does not influence camshaft/valve lift, but can have some adverse effect on rocker arm geometry.

In the future rather than grinding .050 off the tip of the valve stem there are some OEM style mild steel pushrods that are pushrods that are around .030 and .050 shorter than stock and cost less than $20 a set.
