Jim,

Here is a torque chart that I use, it gives the torque for grade #2-#5 and #8....Personaly I wouldn' go much over 35 lb, for a 7/16" studs/bolts..... after installing a few helicoils in these old cast blocks I like to error on the light side....http://constructionmisc.tpub.com/TM-5-3710-200-13P/css/TM-5-3710-200-13P_22.htm

Thanks again. I was thinking 45 ft. lbs so I will go your way. I hope to hear it running in the next week or so. May be back to you if I run into difficulties.

Hi Bill:
Just to let you know that I fired it up yesterday and it ran great. First time it has run in 47 years. If you are interested, check out my project on www.jimmys-durant.com and go to the last page video. You can see it running. Thanks for you interest.

Jim,

Yes, It's always fun bringing life back in these old engines after setting for so many years....Be sure and re-torque the head after it has been ran a bit and warmed up....Looking at pictures on your site it appears that you had as much a problem digging your Durant out of that barn as I did my Flint when I bought it a couple months back.
