brodix catalog for there IK180 or IK200 recomends
champion RN12YC. autolight 3924 for pump gas.
NGK R5671-8 for race gas.

I`m not familiar with Brodix heads but to use a 3/4 reach {RN12YC} plug in a small block head is unusual. BB yes, SB I dont know....

The engine builder put the Champions in my IK200s.

I don't know either thats what there catalog says to use as a starting point.

Brodix may have made the thread length longer in the head for less chance of pulling threads in the aluminum.

Could be, its logical. My A990 Hemi and L88`s use the 3/4 reach but my Darts use R44T the peanut plug on the LS7...and all are aluminum.....He will have to look in the plug hole and check depth and if theres a taper or flat for the plug gasket..
