If those are the TBI heads with "swirlport" pockets you ABSOLUTELY do not want them!
Remember, 416, 601 or 081 heads ONLY for a good port and polish for 305s.

re: the 193's, if you guys will jump over to the TBI forum, you'll see some very impressive post-port work, without removing the vanes...made me do a double take...very comparable (in fact better on the exhaust) than 083's., been a few weeks since I read the thread, but the flow numbers seemed to scream for a single pattern cam...something like 230/190 i/e.

Here's the link, more on the exhaust than I thought.
