You should have a major improvement....due to the longer threaded portion of the plug actually gets in the combustion chamber and NOT causing a hot spot due to the shorter plug. Just did one a few weeks ago....taper plugs and they were wrong for the aluminum heads....and changed the heat range for street driving.

I HOPE it all goes well.
Even if you get the plugs in and it is running fine...I still connect a scanner to is and make sure it is doing what it is supposed to do....and IF it is still running a bit 'funky'...I would obviously check the KV of the plug wires and also fuel pressure...,,,and as much as I hate to write this...UNLESS you know for a fact that the harmonic balancer is NEW...is to check to make sure the notch on the balancer is CORRECTLY positioned and has not spun. AND YES...the outer ring of the balancer can spin...because I have had some that have moved 1-2 inches. This way you know when you go and time it...the notch is correct and you are not setting the timing at a number that 'does not make sense'....because you assumed the notch on the balancer is correct...and it is not. Just a thought.

Timing marks are often off due to the hormonic balancer shifting. Seat of the pants and testing is the only way to nail down an old engine or go through the hassle of finding true TDC. The timing mark wondering is usually caused by slack in the timing chain. The advace is done electronically from the TPS and MAP sensors. I agree with above statements about the timing being bumped to 10-12 advanced. I run my 82 at that level too. The knock sensor will usually pull timing before detonation becomes a problem.
