Take up the gap between con-rods with a feeler gauge when torquing. Is this to keep the bearings/cap/rod square to the journal and arrive at a more precise torque value, and obviously less of a chance to distort the bearings? When torquing the rod bolt it will twist the rod on the journal and possibly bind the bearing against the journal surface, damaging the bearing. It's more prevalent when con-rod side clearance is excessive or greater than factory specs which is common with aftermarket con-rods.

Just because you've built 100's of one family of engines, doesn't mean you know how to build them all....
Had a friend that had the local machine shop assemble his 440 short block. This was a shop that build engined engines for the local napa, and many local garages. They never lined up the hole in the cam bearing that feeds the rockers..... Guess how long that lasted... Had another friend who had a 526 caddy stroker built by a shop that build race engines. This shop has engines that power many cars, that have set records... all of which are Chevy engines.... They went to break the engine in on the dyno and get some HP numbers.... Engine kept popping and sputtering like there was a timing issue. Turns out, you don't line up ther timing gears " dot to dot" on a big caddy... the builder did not know this, it was the first one he ever built...

Don't spend 1000.00 getting your heads ported and pull an intake manifold out of the box and bolt it on Funny you say this, I have two intakes sitting next to my newly ported sb sidewinder heads but just today I was on ebay looking for options...... The holley street dominator single plane ports are so small there is no way to match them to the larger gasket without going through the casting on 3 sides. The LD4B dual plane will take some extensive work that is outside of my expertise and abilities. Hmmmmmm

Make sure the cam goes in the block before anything else.
If it does, degree cam with just the number 1 piston in the block. That came from Dram. I thought it was really smart

Yep, just happened to me. Glad I primed the pump and discovered no oil to the heads before starting it.
