72 duster resto
if the cam i'm buying offers a matching lifter kit, i'll usually go that direction. in the case of howard's i *think* their lifters are made my morel, which are good quality.
you're not going to know if the stock pushrods work with the setup until you start your pre-assembly checks. likelihood is that they will, it's a pretty much stock build, but you always have to check-- especially with aftermarket heads.
you're fine to buy a cam and lifter kit. if you need different push rods it is what it is, the cam and lifters probably weren't the contributing factor-- the machine work and heads would be.
