I have a 96-2000 454 # 12568777 in my Baja. Been running MR 43 TS Delco plugs , but seem to burn cool at low rpms. I looked up casting number on block# 10237297. Turns out that number comes up a Vortech motor. Can i run MR 43 LTS plugs( longer plug) with hitting pistons or valves.

Re: 454 spark plugs

Welcome to the forum
You really need to go to the Adults only and (How to Ask a Question ....)

Your asking about can you use a differnet plug, but all we know is you have a GEN VI block. If we had your serail number this would tell us what heads are on it, along with other items which will effect our comments. My gut tells me that you should always use what is recommend nd deviating can cause larger issues.

Case in point, I have an engine in my shop now which someone put hotter pulgs in, and 200 hours later the engine is damaged.
