What plugs to use with Edelbrock E streets, 440

[moparbud66]

Ok, I broke down and upgraded to Edelbrock E street cylinder heads. I noticed that the thread depth is greater than the stock cast iron ones so I'm thinking that I need longer spark plugs. Am I correct and what is everyone else using for this application? Thank you in advance.

well a quick and easy check of their website states a 14mm x 3/4 reach, gasket seat.

Don't forget some anti-seize to put on the threads to avoid galling.

Are you looking for plug dimensions or plug heat range? I am guessing (and this is a guess) that something like an NGKBCPR6ES might be a decent starting point. It is medium heat range. 7 would be colder for NGK. Do you know what your CR will be with the new heads? I am guessing with that and information on your cam, that someone will be able to narrow down the heat range better. I apologize if I am telling you things you already know.

Thanks guys, I got a set from the shop I bought the heads through. I will keep the never seize in mind. By the way, SHE RUNS GREAT!
