For a modest low cost, for modest performance gains, for ultra easy tuning, and for next to nothing headaches using TBI heads on a stock L31 roller camshaft short block assembly is an option worth considering. Other options available will: add cost, add headaches, increase performance, and add time for tuning.

All due respect Dave, those cams don't even work as well as the stock 201/208 LT1 cams in the 350s. I ran a LT1 cam on a STOCK 299' AWLD calibration for months with nothing more than 14 psi of fuel pressure, 6° BTDC on the timing, and a slight tweak of the minimum air rate screw on the throttle body. It was smooth, made good torque, had a great idle, and gave great fuel economy. Idle was a bit rich with the BLMs in the 110 range but otherwise worked very well. Minimal tuning would have fixed the VE tables and the advance curve could have been quicker with more initial timing to give even more low-end power.
