The way I read it is, if I run stock heads my hp is “X”. If I run aftermarket head pn1234 than my hp is “X” + 5. The reason I am adding 5(or however much) hp is because that is what these heads are deemed to be worth with their ports/valves/chambers/etc.
I think the difference from stock is acknowledged in the increase of hp. What sbf has been approved for stock? Gt40p heads at +5hp? I’ll go for that thank you very much! Lol. |

I'd say not a chance. With the way things have gone,"who knows" is a smarter reply.

Haven't the aftermarket always influenced the Tech Dept?
