If you want to go faster, you could tighten the intake lash .010 and see if it likes it. Then try the exhaust. More compression will help as long as you don't have a big dome on the piston. I am geussing you have thrashed it enough to know what it wants for timing. If not back it down a couple first, and see if it helps.
Did try lashing it to. 024" once cold to be lazy as doing a hot lash makes a mess because these heads don't drain very well. Car lost 2 tenths. If anything it likes the lash a bit loose. Cam is currently retarded 4 degrees also. Tried it 2 degrees advanced, hates that too.
