the tr55 is stock heat range plug gaped at .50 the tr5 is also stock heat range gaped at .35, the tr6 plug is one heat range colder then stock heat range gaped at .35
i used both in ls1, ls6 & 6.0 with good results in stock and h/c/i engines, the stock heat range should be fine unless your running nitrous or FI, one heat range colder is not much of a difference it dont have any thing to do with how much spark the engine gets it has to do with how fast the heat gets transfer to the cylinder head from the plug
so either plug gaped @ .40 or .45 should do you
