Wait up... are they stock Ford bolts or ARP's or a different kind? Different bolts take a different torque setting.

you are right again.....

if you are using afr head .....

Apply moly-oil mixture to washers, and area around head bolt to prevent galling and improper torque readings. Torque to 70 ft/lbs. for 7/16" bolts or studs (289 or 302) or 100 ft/lbs. for 1/2" bolts or studs (351W) in three or four steps following the factory tightening sequence. Then tighten the long (upper) head bolts or studs to 80 ft/lbs. (7/16") or 110 ft/lbs. (1/2"). A re-torque is recommended after initial start-up and cool down (allow 2 - 3 hours for cooling).

if using trick flow twisted wedge.....

Thanks for the link. They're TFS street, going on a 302. ARP head bolts. I assume, follow the directions by trickflow. I wish I had those links before I bought the pushrods. I states 6.750 length. I got 6.700. But it also stated staying within at least .050. So I guess I'm good. But like Eagle said, I need to check the geometry of the rocker vs. valve. If they don't work I could always send 'em back and get the 6.750. I was just hoping to have everything so I could get it done this weekend. Trying to get the ducks in a row.

Hopefully those rods will be right and you don't have to get other lengths.
