Spark plug recomendation?

Hi all,
I have a gen 1 350 with flat top pistons, 062 Vortec heads, and roller cam and lifters. I'm finishing up the build and wondering if I should use the plugs recommended for those heads. Do the flat top pistons mandate a different type of plug?
Thanks a lot in advance for any information!
Scott

You need to use the plug type that fit the heads.

Your just jealous because you can't hear the voices!

Re: Spark plug recomendation?

reach is important, I think you need about 3/4 on those heads maybe, you need to fill in the blanks from there, what you are using it for etc? Probably won't hurt to start with these though R44LTS

ACDelco R44LTS would be a good start.

Thank you all! The car won't be driven much. Once in a while on a weekend to a car show or out for burgers. I'll start with those.
This forum is freaking awesome!

If you were running the same heads and combination before post some photos of the plugs you were running.

If this is a new installation then that won't help us, but the R44LTS are a good start and won't set you back to much.

Run those plugs a few days then pull a couple easy ones and see how they are running. If you don't trust your plug reading skills, post some pictures here and we'll take a look at them for you.
