Spark plug ?

I am installing a 1989 stock 350 truck motor on a 68swb. I bought it as a rebuilt long block. It had some old a.c. r44t plugs in it. Just to keep the dirt out I suppose. I am putting in a new hei dizzy and carb. What plugs do I run ? Someone asked a simular ? Resently and was told r44ts. Dude at auto zone sold me r44lts6. Quite a difference in length between those two. Whats correct ? Gap ? Thanks

Re: Spark plug ?

45 is hotter plug than 44. Depends on what you need. HEI plugs are gapped at .045.
