    Npi heads? Hey....youll be fine with no reliefs. Even if you deck the heads or block .050" youll still be fine. Loads more room than pi heads. Grab a set of 1.840 intake valves and have your machinist guy install them, then port the heads.

    Yes, a mild cam with stated gears will be good. Im more of a spec guy and would rather talk numbers, but to simplify the 270comp will be a bit over kill for the gear youre running. In all honesty, the pi cams are great cams.

    Well I'm thinking of blower in the future.. Like next winter, how would blower cams work with no blower but tuned, or is the option just to replace the 270s for blower cams when I do it? Sounds pricey. I'm also going with a 4:10 set up with edelbrock intake

    Sticking with the stock intake will be more beneficial only because of runner length. If you decide a complete rebuild, then I can see an edelbrock intake benefit. Any cam will run n/a. Utilizing the cams purpose will further potential, but yea...any cam will run n/a.

    Comp 270's are actually decent as blower cams. Many have run them with boost over the years.
