So I bought a mild Howards SBC retro-fit roller cam and lifters set a couple years ago for my Regal project, the engine that I was going to use that was a non roller 2 piece rear seal block had some issues so I sold it and soon I will be looking for a remanufactured short block but most of what I see are 1 piece rear mains designed for the factory hydraulic roller set up so I am wondering if there will be any issues running a retro-fit cam in a later model roller block, my main concern is will there be clearance issues with the link bars.
Also are there any issues using the earlier style double roller timing chain.
