Which would you run if cost was not a factor?

...on a stock ci motor?

...on a 383 ci motor?

I only have experience with Lloyd...it was very positive.

 

I can 100% vouch for the AFR's. I had originally planned to go with Lingenfelter heads on my build (back in the day) and after receiving a set with a pin hole in them I ended up giving AFR a call. Needless to say, as soon as they went on the engine, the bird's started singing, the flowers started blooming...well you get the idea .

 

As a side note, mine are on a 383, but if I were building a stock displacement LT1 I would be using then again without hesitation.

 

I can vouch for the AFR heads, they are probably some of the best I have seen. I just finished pitting together a 383 for my friends 77 Z/28. We are currently breaking it in so no standing on it yet, but man this thing is pretty wicked. The heads were we used were the full cnc'd 195's. They look like a work of art. 2.05 valves, quality all around is second to none, imo! We used an Eagle forged crank and H beam rods, forged flat tops pistons. A bit too mild of a cam for me, but it works. IIRC it is Edelbrock 2102 roller cam. CC roller lifter, ultra pro magnum RR's...And I convinced him to pull the TH350, and run a 700, so he could afford to actually drive it....AFR's are a good choice!
