Curious about AAR/TA Heads

The TA head was a minor 'tweak' that was sort of an 'easy to do' mod that might pick up a little HP after all the port work was done. It wasn't a 50HP, or better, deal.

I wouldn't pay a nickel more for a TA head unless I needed it for a resto. The minute I needed a better head than a stock 340....I'd be looking at W heads or aftermarket.
