Comp Cams 735-16 Titanium retainers. New, never used, designed for triple springs with 0.050 extra installed height. These retainers provide a 2.000 installed height on Indy heads when used with the Manley 13198 locks. I used this combination on my 514 race engine to run 0.800 lift with a triple spring. These retainers were spares that never got used. The retainers are $388 new from Summit, I'll sell these for $200, shipping included in the US. PM me on the board, PayPal preferred for payment. Thanks.
