What About Edelbrock 340 Heads?

IDK, but
I have a pair of OOTB closed chamber Eddies on my 367 streeter. Car went 93 in the 1/8th at 3467 pounds, with a 230cam. I was real happy. They have made it to over 100,000 miles now, and still going.

Edit: At 10.9Scr, car is very snappy with a 3.09x3.55 starter gear, and makes enough torque to initiate a spin at part throttle with 295BFG TAs. It will carry the spin to past the legal speed limit anywhere in Manitoba. It will easily initiate that spin in 1.92 second gear at 50mph(4200rpm) with just a foot stomp.
I have heard that BFGs ain't much for traction, so I include this; The car does the same with nearly fresh BFG 325/50-15 CompTA DragRadials, so I'm still a happy guy.
The bottom end is about as plain as can be; just a basic 360@040over with stock crank,stock rods,ARP fasteners,and KB107s at .005 pop-up, +/- .0015.
I run it at 205*F, and fresh cold air down the top, TTIs and with twin full length 3inchers. I got no regrets about the hole in the hood. I run the air filter on top of the hood, unconventional I know, with a large-plenum insulated box under the hood connecting it to the airhorn. No scoop.
93mph IMO is pretty good with already five year old heads, and probably close to 50,000 miles at the time.
IDK where the power comes from.
