I finally got the numbers off of the 454 that I am going to be getting. The cast is 361959, I know 70-90 454. But, I also have other numbers. Pad behind alt = C3Z112653 and pad behind water pump = T0907TSB. I know the T= Tonawonda (sp) and the 0907 is Sept. 07. But what is the TSB? The head numbers are 316236. Shows to be oval port 454 open. Are these any good? Where can I find the info online?

Do you live on the net? Man, it was less than a minute and you responded. I got the info on the casting for the heads and block there, but could not find anything on the other numbers. HP rating?
