NGK Double Platinum Plugs
Has anybody ever used the NGK Double Platinum plugs? (part# PZTR5A-15) I know most use the TR55 copper plugs but im looking for a plug thats going to last a long time because of how hard it is to change plugs on an LT1

I doubt that most people use TR55 coppers. I don't know which plugs those "double plats" are but some use the TR55VX plats and the iradium plats. Perhaps the doubles are the latest version of the plats.
Yes, since changing the plugs is not an easy job, going with longer lasting plugs might be for you. The coppers should last a couple of years if you aren't too hard on them and they are supposedly better conductors than the longer lasting plats and others.
One shouldn't consider the cost as a factor when doing plugs. Paying 6+ bucks per plug becomes a non-issue when you put off having to change cheaper plugs more frequently. And I doubt that the coppers will give you any gains. JMHO
