I think it depends whether or not you want the stock chrome shielding reinstalled afterward.

HEI's are great buy new plug wires too. I like the kind that run under like the stock ones. Also if you have dual quads a large cap won't fit. If I were to do it again I would do a small cap.

For me, I have been REAL pleased with an electronic conversion, such as PerTronix. It permits retaining the stock shielding, which I really like on these early cars. Performance is excellent.
