SBC SB2.2 Jesel Rockers (4) DBAL 1.75 (4) DBAR 1.75   (4) DBBL 1.70  (4)DBBR1.70 . This is a complete set 1.70 Intake 1.75 exhaust.  The issue with these is the ziplock bag these were in got damp and the aluminum has some minor corrosion and a few of the rollers have some minor surface rust . They are in nice shape besides that. Great ratios . Would pair well with other almost set in another auction so you can have spares . Hard to find .  Bid today and save.  Thanks for your interest
