HEI Conversion, need opinions

[Madbomber88]

I'm going to convert my stock 72 K20 350/SM465 to HEI next weekend.
I just picked up a factory GM HEI distributor on ebay out of a 76 for $14.00.

Now I need an HEI rebuild/tune up kit. There are three that I am looking at... The MSD Ultimate http://www.jegs.com/webapp/wcs/store...tegoryId=11579

Moroso super HEI

Or Pertronix Flamethrower

What's the best bang for the buck? Soon to follow are a new carb, intake, cam, and headers.

Thanks!
