I find that the Allen key head just doesn't fit as tight as a Torx key. The Torx key has no slack in it at all and when I'm torqueing them down the snug fit of the Torx head is reassuring regarding accuracy.

You could just pull one out and swing by home depot/lows and measure the thread pitch there. If you can't find the screws locally, try mcmaster.com. You can order damn near any fastener you'd ever need there.
On the site, go to Screws & Bolts > Socket Cap Screws > Star. That'll get you in the right section, then you can select all the other specs. I go there when I can't find bolts I need anywhere else.

i always do ring screws @ 25 and base screws @ 30 but i could be the one who is wrong

A loose fit or a tight fit on the fastener don't make a bit of difference running torque for a single direction. It matters when you have an impact type fastening cycle. Ingersoll-Rand has curves of this kind of data, I spent 2.5 years working for them during college doing all kinds of engineering support for a lot of tests.
There's a downside to Torx that I don't like. You strip a torx you're boned, it needs to be machined out.
You strip an allen key you can almost always jam a torx wrench into there and get the fastener out without the use of a machine shop.
I would not bother replacing those fasteners for both reasons I stated: It doesn't matter for "precision" in the torque check, and you can be screwing yourself down the road in terms of taking them on and off.

I understand that as long as the tip is not slipping inside the bolt, torque accuracy is not affected during one directional movement.
I do however feel that torque accuracy is affected by how that torque is applied. What I mean is that in order for torque to be accurate, it has to be applied directly along the bolts axis.
For me torx screws just seem to lock the tip in tighter with less slop. As a result, as I am torquing the bolt down, its easier to keep the tip lined up straight with the shaft of the bolt.
For such subtle differences in torque measurements as you get with inch pounds, I think it makes a difference. In the end I feel more confident with the accuracy of the results.
Just my opinion.
