That leaves my Ps out.

Ps are allowed, larger valves (1.84/1.54 I believe is max) are allowed as well as valve jobs and milling... the intake and exhaust ports cant be touched. There are ways around every rule and whose to say who does and doesnt "cheat" but the rules are pretty strict.

Don't you take a weight penalty with P's?

 

[Mr. Rustypwnz]

why would there be a penalty?

Like I said, that leaves my Ps out.

Yes there are weight rules, long tubes add weight, Ps and regular 40s add weight etc... I used to follow NMRA years ago but have since stopped. The cars have gotten past the realm of street cars and the amount of coin it takes to even go to an event is insane.

Still impressive though!

mine have been ported and supposedly flow in the 265-270 range,

Id double check that, thats a lot of flow from a cast iron head that originally only flowed like 145ish or so
