I'm currently installing heads on the 350, finally switching the 305 heads to 350 ones. What should all the bolts be torqued to? I am using the old bolts again, do I have to torque them higher because of threads stretching?

What is the procedure for tightening the rockers, are they all at a specific torque?

Also, My pistons have stamped on them 345NP .030 So I know its 30 over, does anyone recognize the 345NP? They are a flat top piston but I would like to know the compression ratio.

Thanks for the help

P.S. I really like the new board!!
