I'd be careful there. I believe that the OP has a vortec 350 block. I know that my 1997 LT1 blocks use a 1/4-20 button-head Torx fastener to secure the cam retainer plate. I don't think that GM abandoned American fasteners until the LS series was introduced. Clearance for the cam retainer fasteners is very close and he doesn't want any contact between the cam sprocket and the cap screw head.

Re: Camshaft Retainer Plate Bolt Size

Chuck. Are those 1/4-20 button head bolts 1/2" in length? By the way, getting the hardware for the RMS housing was much more difficult than it should have been when dealing with these GM dealers, but have it coming on Monday. Thanks again for the assistance!
