Currently have L48 with Holley 750. Looking for good manifold and head combination for street use. Don't want to loose low rpm torque to gain high rpm hp. Currently looking at Edel perf vs. perf rpm packages.
Cam suggestions wellcome too!

the nice thing about good, properly sized aftermarket heads is there is no down side, when I swapped mine out, got power everywhere!
Virtually any aftermarket head, 64cc chamber & around 180cc intake port will do a great job on a street combo. a 70cc head with a thin shim gasket would work too, with tighter quench. either would be around 9.5:1.
I have a perf rpm on my 327, and like it a lot. course I switched FROM a torquer 2, again, more power from idle on up.the 2 changes together extended my rpm range nearly a thousand on top, AND on the bottom too! (even with a stock cam)
