Performer 318/360 intake

To really make those heads work, you gotta get that dismal 140psi up to at least 185, and 195 makes a killer street machine. Ask me how I know.
Until you fix the pressure issue, I wouldn't waste my time with anything else...... unless you have an auto-trans, then I'd order a performance convertor, one with a much higher than factory stall.

Semi agree. While adding compression is a big factor, it’s not a 100% needed thing. More airflow over the stock heads is going to make more power.

Not taking advantage of the cylinder head the way the OE poster describes, is IMO, a terrible waste.

Even on a low compression engine, the added air flow will increase power. Leaving added compression and leaving a low lift cam inside is the horror. Even a modest increase of a camshaft would be great.
