The longer valves will give you some better spring choices if you are going with high lift. Dvorak sells stands that move the rocker up, I think .100. That would work. Maybe. With Hemi rocker gear, you never know till you try it.

Thanks for the replies so far.As far as stands I already have a set of fixed stands.From what I can work out you gain an extra .040 thou of installed height the other .050 thou has been added to the tip (.250 instead of .200 std) Would it be possible to remove .050 thou from the valve tip since I will be running lash caps? Because the valve seats are uncut in the heads would it be possible to get the seats cut a little higher to help reduce the extra long stem?
Might not be a bad ideal to call Tim at FHO. I think he buys valve blanks and cuts his own lock groove. Buying blanks allows him to order the proper lengths.
At first glance, cutting the tips and using a lash caps sound like it will work, but once you cut the tip you remove the surface hardness. Not sure if the cap will move around and mushroom the tip.
