It's relatively easy to tell if that is your hang up.
Remove the flywheel and see if the bearing/flywheel clears the input shaft on your trans.
You really REALLY need to have the clutch disc perfectly centered for it to all slide together properly. The margin for error is very small.
As you can see the clutch disc can be pretty off center and the trans will slip into that but then get stuck because it's not lined up perfectly with the pilot bearing.
Did your kit come with the plastic centering tool? I personally dislike those because they're very loose fitting and can cause centering problems.
If you are using the plastic one loosen up your pressure plate again, put the tool back in and wiggle it up, down, left and right, get a feel for EXACTLY where center is then tighten the pressure plate down again.
You MUST hold the tool on your center line as you snug down a couple bolts so the pressure plate then keeps the disc from sliding.
I have the best luck centering right the first time with sockets and long extensions.
I find a 1/4" drive socket that fits PERFECTLY in the pilot bearing then I find another 1/4" drive socket that sits PERFECTLY in the clutch disc and use those to center it. Hard to describe, much easier to demonstrate in person.
If I did Honda clutches regularly I would keep on hand an old input shaft out of a transmission for centering the clutch. NOTHING beats this.

The clutch kit did come with the plastic centering tool and I just utilized your suggestions regarding the pressure plate and the plastic alignment tool. I think that tip helped more than previously, because I've seem to have gotten closer.
Instead of eye balling it, I decided to measure the gap between the engine and transmission with my digital calipers.
At the second transmission mounting hole, the gap measured out at 0.32 inches towards the top of the engine & transmission and at the dowel pin at the front of the engine, the gap measured out at 0.25 inches.
It was then that I decided I was perhaps being too cautious & conservative and got behind the passenger side portion of the transmission and wrestled the thing forward. I rocked & shook the transmission until I heard the "tink" of metal joining together & that's when I took another reading.
At the top of the engine towards the second transmission mounting hole, the gap measured at 0.14 inches and at the dowel pin, the gap was measured at 0.11 inches. The last thing that I'd notice was that whenever I put pressure on the rear portion of the transmission, the gap to the rear dowel pin closes off completely.
In short, is it now safe to bolt the transmission onto the engine?
