26918 springs

614-16 locks (10* +.050")
4705-16 spring seats
On a stock aluminum LT1 head this setup should
result in about a 1.75" installed height. You may
want to send Bret/SStrokerAce an email. He can
probably get you the parts at a good price.

I belive you can use 7 gegree hardware as well (so I've been told):
Comp 648 locs
Comp 787 retainers
stock seats
installed height= ___?(maybe someone can fill in the blank here)

Nearly every ti retainer I have used increases installed height as well. Many large diameter Comp retainers raise installed height .080". I have no experience with the nickle sized beehive ones, but they may help installed height as well. Of course if you're using ti retainers, you're probably using 10deg locks, and have a + .050" option so the point may be moot.

I have spent hours installing and uninstalling both the 7* and 10*
hardware with the beehive retainers on stock heads. As Bret says,
the only way to go is with the 10* super locks (+.050" is preferred).
The installed height of the 7* hardware is higher than the 10* if you
use the regular locks, but only by about .030". Going with the +.050"
locks gets you another .015" to .020" in installed height, which only
gets you in the 1.75" range with a .062" seat.
The 10* retainers (reg and ti) install at the exact same height, it's the
locks that make the difference.
I hope that all made sense?
