twin-plug aluminum hemi heads
 

I need info on the application of these heads . Are these really a NASCAR application? Anybody know who made these heads or who ran them on their cars?

Appreciate it? https://www.yenko.net/ubbthreads/imag...lins/beers.gif

I don't know about NASCAR but every prostocker in the early 70s ran dual plugs.

I don't believe the dual plug heads were ever legal in NASCAR, especially not in the early 70's. Neat pieces, nonetheless.

the Motown Missile Pro Stock Challenger had those heads.
