Help me get into the 12's for cheap

You ran 14.80's with stock heads, cam and converter. Can a really good head, cam, and converter combo push you to a 12.99??? Boy, them are the kind of projects that I love.... and might be cheaper! How about a set of 308 heads off of a 89-91 360. Cheap, and flow very well, especially on the exhaust side. Should be able to grab a set for cheap, cheap, cheap. Then a .455 lift cam from MP (idle -5800), and a really good converter. Hmmmmm...... this all could be done for less than 800 bucks.... And perhaps .030 KB pistons??? puts ya around 1200.00. I bet you get your 12's
