As long as the engine is kept basically standard, then the camshaft I'd recommend is the one based on the Erson RV10 grind as these are ground by many aftermarket camshaft companies such as Dynotec. We actually use to put these cams in our standard 2V Cleveland builds as they were the same price as a stock grind and would give the engine a bit more pep. They idle nicely, excellent vacuum and terrific drivability. The specs from memory are around 210@50 and valve lift is 484 on both intake and exhaust. As for your springs, they do get away with the standard type springs, but we would use the ones with the wound dampener in them. Standard pushrods and rockers are fine as long as they are in good condition, but just make sure the lifter pre load is set correctly, which usually requires shimming were the rocker fulcrums bolt to the heads. Being a stockish 2V engine they don't require split duration or extra lift on the exhaust side like a 4V. Even if you're using a 4 barrel intake and carb and even headers, this camshaft will still work very well in your application. Another thing to look at to give you the best performance/economy is your distributor. If you're still using points I'd suggest putting a Pertronix kit and also making sure the bush is in good condition, or buying a good electronic distributor (not Pro Comp or cheap eBay crap) I set Clevelands at 14-16 initial and 34-36 total at 2800-3000 RPM. Good luck with it all and if you need any further advice, remember there is a lot of people on here only too happy to offer good advice.
I just had a quick look for the cam specs and are as follows: 208@50 in & ex, lift 484 in &ex, 112 lobe separation, advertised duration 280/280 in & ex. Like I said, these cams work great in standard type engines and I have built plenty over the years with them fitted, so I know how well they respond with them.
