They are a lot less trouble than headers. Nice product. I have a set and believe they will fit the Johnson with no trouble.

Headers will give you more low end tq. You are after that.

My dyno tests only show problems with the power when harmonics hit at high rpm. Stroker is not aiming to remotely go to those rpms.
