Thanks all, Additionally 8 bolt or 14 bolt - whats the difference? Can the 14 Bolt heads fit on a factory block?

Both will fit on either block. You need different rocker set ups for each. If you have good roller rockers already for irons id get the 8 bolt ones to save on rocker arms.

I have the TA's, but would recomend taking them apart & cleaning up the bowls. Mine had a lip from where they machined the valve openings, but other wise have been very happy with them.

Going to be buried in this.
Champion for me. Tom is the best for customer service. I had some issues with the heads I bought second hand and not only did he answer all of my questions, but got me fixed up with all of the stuff I needed to make it right. One of the best venders on the board. THANKS Tom!!!!!

#25, like my sig says though, it was a way rich tune, 8:1 - 8.5:1 AF. After the work my dad did cleaning the heads up, a proper set of plugs, and a better tune, it should see mid tens without any problem.
