Which plugs to buy and where?

[FordStang]

Just wonder which plugs should i buy for my setup and what should they be gaped at, Look at my Sig for my mods including what heads i have thankyou

I'd say Autolite 3924's gapped at stock (0.054"). I'm assuming your heads take the same plugs mine do, you may want to check to be sure -- whatever you do, don't use plugs made for iron heads!

BTW, your might choose a different color for your signature text...

The RC12YC looks identical in physical specification to the Autolite 3924, so it's a matter of preference.

That doesn't look like a correct Autolite part number to me, are you sure it wasn't 3926? 39 is the series, 26 would be the heat range. Stock is 25, I run one heat range colder -- hence 3924.

Champion plugs blow chunks. Autolite 3924's gapped at .045 is what you need for aluminum heads.
