Junkyard 5.9L Magnum + Edelbrock LA heads build

Yeah it makes me want to make sure my torque wrench is accurate before putting the heads on, I know the head studs will probably put different loads on the cylinders but I don't think I'll be taking this thing another 50k miles to make a difference.

I read about the G3 Hemi head bolts in an SAE article about new manufacturing methods used for the engine, the authors didn't go into much detail but engineers basically found the head bolts could be made shorter and somehow pull the clamping load more from around the cylinder than the cylinder itself. I have a 5.7 short block on a stand in my garage I should take a look...

If you are using ARP studs, their lube, torque numbers, and procedures, the clamping force is gonna be something like 50-70% higher. That force all comes from the block at the threaded end. So, yes, it may be different; it all depends on how the material twists/distorts to hold varying loads. In the case of that 4 banger block distortion, I did not find any increase in distortion beyond 25 ft-lbs or so on the top bellhousing bolts... so it's possible you won't have any significant change. The only way to know is to assemble the heads on without a piston in a hole, and flip it over and measure the bore at the top once all is torqued.

OK on the other bolts....if you ever run across more info, I'd like to know; tnx.
