those using Comp 987 dual spring setup, need urgent HELP!!
OK....below is a problem with incorporating the Comp 987 dual spring setup with LS1 style Ferrea valves. Read:
"I received the Comp. Cams 987 springs and they look good. I also
received the Comp. Cams P/N 730-16 Ti retainers which they recommended for this application... The
problem is, they are 10 degree retainers and no valve
lock (keeper) exists that fit the LS1 valve and this retainer. I also
tried a 7 degree Comp. Cams retainer but that
will not work with the LS1 style valves either. There is no LS1 style
valve keeper (7 degree or 10 degree) that will
work with any of the Comp.Cams retainers. Comp. Cams has only one LS1
style retainer (P/N 754-16 with 6.2 degree keeper
angle) and that is for a 1.250" diameter spring and will not work with
the 987springs. I have talked to both Comp Cams
and Manely about this problem and they have nothing that will work...
The problem now is that with LS1 style valves (2.05I, 1.6E, Ferrea's),
the only keeper that will work are the stock GM
(6.2 degree) keepers. I am now searching for a retainer that will match
the 987 spring AND the LS1 valve and keeper..."
Does someone have the answer??? urgent help needed quick!! thanks in advance.

Call Brian @ TEA, I have 987 with Ferrea valves on my 5.3 heads, 270-782-6397 , he sets up all his LS1 heads with this exact setup.
