Stroker cam suggestion

If you're worried about power brakes and idle, go with what Porter told you. He didn't just fall off the turnip truck and I suspect he, in talking with you understands what YOU want. That's a clean idle and power brakes.

Tighten up the LSA and you will make more mid and up power, but the curve will be a bit more narrow AND a bit more peaky, meaning after the peak the power curve will drop faster.

For you, I'd go with the Porter cam. For me, it would be totally different. Since I don't pay your bills...id follow Porters advice.
