Re: Camshaft type?
In a factory roller block engine, there are three bolt bosses in the lifter valley, on the main oil galley, that the 'spider' retainer for the roller lifter locks, is bolted to. There are also two bolt bosses behind the timing cover for the camshaft retainer plate. You can go with an aftermarket type of roller setup (as Blue Bowtie says, these have been around for decades) with lifter pairs that are attached to eachother and a camshaft "button" that holds the cam back in the block.
Most aftermarket roller type cams are machined from billet steel - a steel rod in untechnical terms, and are sufficiently soft on the distributor drive gear that you MUST run a bronze distributor gear to prevent the distributor drive gear on the cam from failing and taking out the distributor - and oil pump.
Roller lifters must be retained in the block and not allowed to spin - if one does, the damage is catastrophic.
