You know, a lot of this will make almost no difference whatsoever in your engine. Schneider grinds a 264-74F AMC 199-258 Solid Lifter Camshaft. It is all you can use on the street and will be more than lumpy enough to make people take notice. I've ran their 260/270 grind in a 261 punched to 270 and it was almost too much for a daily driver. Use the stock 1 inch lifters and avoid the hassle of an unknown with the VW lifters. Are they even compatible with the Jimmy cam? Check what it's made of. Use your money on a good head and block. 302 head if you can, 270 block is better than you have. Make life easy on yourself.
