How many of you do or don't hone with torque plates and what's your experiences? I noiced one of the engine masters engines mentioned not bothering with it. I'm guessing it all depends on how rigid the cylinder walls are? Has anybody ever measured the cylinder walls with then without the deck plate to see if there's distortion and how much. My guess is that maybe there's a little power to be had there but maybe not.
It was worth .7 on my buddys V6 stocker.

My machinist told me that BB Mopes usually distort quite a bit...He told me how much the block he just machined for me (400) distorted, but cant remember the exact specs. Sounded like a pretty good amount.

Details?
I mean 7 tenths. 3.9 V6 in a Dakota. Same exact specs, cam, heads, intake everything except the shortblocks. The first one was not honed with a plate. The second one was and it picked up 7 tenths and became incredibly consistent where before it wasn't. YMMV

back in the day 1993 ish I was building a new motor and my machinist was going to use a torque plate. he showed me the cylinder bores perfectly round and hone ran smooth. Then he bolted the torque plate on to simulate the head being torqued and re measured and dam it distorted the cylinders a lot (pushed into the bore at each bolt hole!) then he ran the hone and it was rough he said you have to take the high spots down.
I wonder how much less studs distort the bores?
All the ones i've done pull the cylinder in at the bolt holes..it usually takes .002-.003 to take the distortion out

take perfectly round cylinders, attach a deck plate, and remeasure. you will be amazed.
for what is the good life if not doing things thoughtfully?

Its worth mentioning that the heads are not the only thing that can distort it, albeit they do the most. Many engine shops will have you bolt as much of your setup on the block as you can including engine mounts and whatnot.

Bottom line....better ring seal, longer life, more HP/torque. Some people go so far as to install a torque plate on each head, use the same style head gaskets as will be used on the final assembly, run warm water through the block, torque the main caps to spec.......every little bit helps. Diminishing returns, but returns none-the-less. (Certainly can't hurt!) It's just a matter of how much time & money you want to invest.
As with all things stocker related, one single thing will not typically make a huge difference. Its the combined aggregate of all those things that results in a fast car
