I ran a search for these heads and I came accross some threads in which Jeff participated, he kinda had the same opinion about these heads just like a couple other guys I asked for info. I am not calling any names though.

Like I said, I dont have these heads on any motor, I havent even held em in my hands.

On another note, I do have an engine running 440 source heads, rods and crank. It runs perfect. No issues. I dont think a Callies crank, Oliver rods and Edelbrock heads were a necessity....so far!!!




That's what I thought. Jeff is very well respected within the industry. I wonder how these heads would hold up under boost?




What I quoted was not Jeff's. It was straight from another reputable head guy.

But you can run a search on here and will find out what Jeff thinks about em.

I will stay away from this thread as I know ZIP about heads. You guys try em on and lemme know how they hold....I may then buy a set.
