What is it ? You ever add more ? Hemi is 80 with ARP lube. No. I assume a wedge is the same torque.

the problem with put higher torque is it starts distorting cyl walls from what they were honed with torque plates

I have been known to give them an extra 5....I have seen enough variables in torque wrenches to warrant that. on head gaskets I would rather be a smidge high than low.

the problem with put higher torque is it starts distorting cyl walls from what they were honed with torque plates Excellent point and worth considering while using a stock block. This last build i used 30wt oil and only went to 70lb and it was sealing NO PROBLEM with about 750 n/a. One thing to consider is that with both an aluminum block and heads they grow and additionally load the fastener.

Post a pic of the spec sheet Stanton When you make power like I do, even good parts are at there limit. I tryd to talk to Indy (Ken) about upgrading to 1/2 inch studs and he kept telling me I need to put one of there solid blocks in it. After enough of that I finally told him I have a solid blocks for my next combo but it ain't cast Indy [censored]. It's BAE lol. He was done after that, so I just put new rods and bearings in it with valve springs and same ole 440Source crank. Still one of the fastest 440-1 combos out there.

Post a pic of the spec sheet Stanton Sorry Bud, I misread your title ... mine are head BOLTS - not studs.
