Did you use those "spreader" washers? They were on v8's, not sure about the 261. I use a product called Hylomar blue on both sides of any and all gaskets, I think it comes from the airplane industry and is also used in marine so its good stuff for sealing without being permanent.
I just tighten the screws by feel, hard to overtighten a phillips screw head as compared to a bolt head?

Thanks so much gents. I went 24" lbs and even that seemed too tight. I backed off and snugged them to what I thought appropriate. Scary that....
Yes, did foot pound inch pound thing, valve body on a C-6 '72 Lincoln. Sickening feeling as I felt it stripping out as I spun the bolt in and realized what I'd done.
Bit of JB weld, back it went, fine 10 years later.
