McGurk supplied a steel cam, .990 roller lifters, dual valve springs and push rods. One of the inner springs broke and subsequently that push rod bent. The push rods were replaced with Smith rods but are the wrong length for solid lifters. No other damage. I replaced the intake valves with PG units and installed dual Buick 455 springs rated at 320 lbs. The three carbs are mounted on a Offy intake (plenum). The rollers only have about 3-4 total run time and look brand new although it is my intention to use new flat tappet solid lifters.
Thanks
