...Sure! Wanting A 40% Increase in Clamping Force, with the FINE Nut Threads, on a Stud, that Bottoms all the way to the Bottom Length of the Blocks' COURSE Threads, Is Paranoia in your view? When I use to use the Factory Bolts I, like you, was advised to torque the Heads to 90 FT/LBS (you stated 95)...The head gasket Blew when approaching 5700RPM. I replaced them, torqued to 95, a Gasket blew a second time*. The Factory Manuel States 'BOSS 351= 125 FT/LBS'!! My C.R. is 10.5, I then Installed the ARP Studs, as mentioned earlier, called up ARP, I think They have done a 'Little' Testing on their own, their advise...Iron Heads on Iron Block 135FT/Lbs, on the Fine Threaded Nuts?! This while the Engine is In the Car. Torquing while leaning in over the Fender! Yes, the Heads CAN be slid up and over the Studs!! Took all the strength I had to hit 135.

Engine has been running Perfect ever since! Took It to the Desert at 118F Degrees, Never got Hotter than 195F, Period!

And try using 'Head Bolts' in a Aluminum Block, and see what Happens!!

* Make No Mistake, this was all on Block and Head surfaces that were Re-Dressed for Flatness and Accuracy. And I think I know a Little Bit About a 'Torquing Sequence' and More.
