My engine builder wants me to get a 4 deg crank adjustable, torrington bearing on cam gear, dbl roller timing chain for my engines. The block is a MKIV, cam shaft is a flat nose hyd roller (couldnt get a stepped nose when the cam was ground), we are using cast aluminum timing covers and Crane roller cam buttons. He wants me to get 2 std lenght timing sets, and a -.005 set because one block had the mains line honed and hes not sure if a std chain will be too sloppy. (he did check the mains on the other engine and the alignment was fine). He is suggesting Rollmasters, but I cant find who sells them now. Any other brands that fit the bill
