Part 2 ov my welfare warrior quest. Headers.

70 Challenger, stock 67 383, 4-speed, NO power options at all. Stock suspension. Will be using a Lakewood skattershield and block saver though.

I have a barely used set o Hedman shorties for a big block B/E car. How bad are they performance-wise over the usual long-tubes (Hooker Comps lets say)? Closer to HP manifolds in performance? closer to longtubes? The exhaust behind them will not be a limiting factor... at all.

Any issues with installation in my combo? I cannot think ov an easier E-body big block install than mine...

How about changing spark plugs? They've GOT to be better than Hooker Comps...
