Magnum EQ Heads, what alternator fits?

Has anyone on here upgraded to magnum heads on their LA block, and if so, what alternator and bracket setup did you use?

Original engine is a '79 360 in a LRE, stock electronic ignition and square back alternator. 1 piece alternator bracket and large idler pulley bracket in place due to no A/C. I planned on using all my accessories off this engine and putting it onto my new one...unfortunately this idea seems to be fighting me at the moment.

Engine on the stand being put together is a '72 block with EQ magnum heads. I can easily modify the one piece alternator bracket to mount correctly (shorten by approx. 1/2"), but the issue I'm having is the alternator itself is contacting the front of the head.

Has anyone been successful in using a square back alt with mag heads. If not, where there any years of a round back alternator that will work with the stock '79 ignition system?

Thanks
