HOTTEST and COLDEST PLUG???

Can anybody tell me the Coldest to hottest plug to use with DOVE heads W/out using adapters? I'm looking at stocking up on some plugs and would like to know what you guys recommend. I wouldn't mind knowing each the brands you guys are using too.

I depends on the application, Blown? No2? Compression? Drag? Endurance? Street?

I drive it on street and track. See's mostly track but just under 10:1 compression. and set-up of NO2. Right now concentrating on all motor runs till I get the tune right.

The Factory Heat Range is Probalby sufficient at 10:1, and go colder depending on the shot you intend to use.

looking for heat range reference numbers. Thanks

This was already covered in the N2O section at length.

it was discussed primarily for cold plugs. I'm looking for a guide line for both hot and cold plugs.

I wouldn't know why anyone would go hotter than the factory plugs.

that might confuse him, he probaly has the big plug, and its hard to find a brf or bf 32 these days, w/ 10 to 1 or so id start with a brf 42, your best bet would be buy the adp's then you will have all kinds of choices , they use the .750 reach, warsher type,
