CONSISTENCY and REPEATABILITY ,rather than exact torque, is the key, if your off a ft lb its not catastrophic.
Ive used both a SEARS and a HOME DEPOT TQ Wrenches FOR MANY YEARS. built over 150 engines and had zero problems
consistent technique and consistency in the way you lube and work the torque loads up in stages and having the bolts and studs lubed and cycling, the bolt/stud up to the recommended torque and loosening it and repeating that process several times tends too give much more consistent clamping load results, AND ITS A GOOD IDEA TOO USE ARP FASTENERS
HARDENED washers DESIGNED FOR USE WITH MATCHING ARP HEAD BOLTS under the head bolt heads are ALWAYS A GOOD IDEA, they reduce friction and gauling and spread the clamp loads and tend to make the torque readings far more consistent, especially on aluminum heads and when the correct lubricants are used , use of standard soft iron washers or lock washers are a bad idea


cleaning threads before assembly is always a good idea

check manufactures tech guide info

having consistent clamp loads are mandatory for proper assembly

btw rod bolts SHOULD have a stretch gauge used but its not 100% mandatory, cycling them up to spec and releasing the tq then repeating several times with a tq wrench, following the APR instructions gets you very consistent results IVE checked the tq wrench results with the stretch gauge

lets assume your looking for a 3/8" drive inch lb torque wrench to tighten little things like intake bolts, logic should tell you that a decent quality tool will not be dirt cheap, and that you don,t need the best available tool for that use so you start pricing your options
the whole OBJECT of you using a torque wrench is to allow you to maintain consistent TORQUE values, do you really think the HF torque wrench will be consistent, when most other sources what 4-5 times as much, think it thru, obviously you don,t need a lab quality tool, but the cheapest option is not likely to be a rational choice either.

NEVER USE A TORQUE WRENCH LIKE A BREAKER BAR TO LOOSEN BOLTS as it TENDS TO QUICKLY DESTROY ITS ACCURACY & consistency

Id point out that a bit of thought as to the direction of forces when your torquing your main caps or trying to rotate your engine location will help a great deal, ESPECIALLY WITH THE SMALLER BASE ENGINE STAND DESIGNS
more than one guy has failed to pay attention to that and placed a good deal of force on the end of a torque wrench or breaker bar and flipped the engine, off balance.....trust me when I say your first instinct is to try and catch or push the engine back as it falls and you are not going to win that contest....if 600-800lb of engines headed to the floor you better NOT get in the way, so its best to use a very stable wide base engine stand and pay attention to keeping forces along the engine block center-line.

this picture tends to make me think this guys NOT thinking that factor thru, moving the handle, on the wrench 90 degrees could lower the engines tendency to tip.

SBC HEADS

Big Chevy
if you don,t have a particular engines torque sequence its a safe bet that you start with the center head bolts and tighten each , in stages in a spiral outward pattern, then repeat the sequence with each increased torque setting moving in that same outward expanding spiral increasing diam spiral moving from the center to outer bolt locations.

dip the head bolt threads in sealant before installation to prevent coolant leaks
