Mike, run the NGK V-Power TR55. You won't have any problems.

I did pop iridiums in and can't say I noticed a difference from the TR55'* to the iridiums..

One thing is that I went to the platinums and it ran fine ( on the blown engine) , also my Malibu comes stock with the platinums.
I am guessing to keep it at a 0.60" gap too then.
Step one will be finishing the car today or tomorrow and get it running first. I already have brand new plugs in it for now.
Once all is good ( crosses fingers), then I will be looking at the plugs again. It was just a question I was asking myself while reading the Haynes manual to double check on the gap, ( I couldn't' remember if is was 0.60" or 0.65"), and noticed that they call for different plugs on the 88 engine ( new engine) and the 89-91 engines ( old blown engine), then I got to thinking, "HMMM I am changing the ignition so what effect will that have", or something to that effect, it was that voice in my head anyhow, LOL.

Conflicting reports in that thread. Having previously run 0.045", my father and I had a little discussion during a plug wire replacement and plug check. And because there weren't any issues, 0.045" is what stayed.

Also my car originally called for R44LTS6, I have used R45LTS6, Ac Delco Rapid Fire 3 and 14... They all pale in comaprison to the TR55'*

With my Magnavox system I always ran 0.60". There was a slight miss/stumble but my 03 Malibu does the same thing.
I did have one cylinder that was low ( low compression) but it ran fine for over a year and a half before it blew.
Once I get the new one running, expect an auto-topsy to be performed on the old engine, with pics too.

Funny thing is that the parts store that I am getting the gaskets for to get my car back on the road, told me NOT to use the TR55 on that engine and to stick with the Delco plugs only, go figure.

I was always told by my dad who was a mechanic for 15 years to use the same brand of spark plug that the manufacturer used when the car was built.
