Here's a couple of good reads for shorter valve seals. http://forums.hybridz.org/topic/25807-improved-l6-valve-stem-seals/   http://forums.hybridz.org/topic/68120-problem-with-viton-valve-seals/  I've read anything over .460 needs stiffer springs and the shorter valve seals.

I put the Felpro SS72686 on my stock E88 as a practice run for myself.  They're a little tricky getting them down without going too far.  I used a deep well socket that rest on the metal part of the seals and drove them down with a rubber hammer.  If you take your time there are easy, after the first one.  

Thank you very much. I will install shorter valve seal just in case the camshaft have too much lift. Now the camshaft is on the way to delta, engine block going to machine shop soon, I'll keep working on the head. I guess I'll start buying parts now.

did delta give a turn-around time?

Nope. I'll check with them before they start regrinding.
