Conceptually, when you place a different hp factor on an engine because of the use of replacement heads (aftermarket or OEM), you have essentially created a new engine for the books. The problem is the way that classification is calculated since it uses a weight break of one rating and then the weight of the new hp factor. Eliminating the differential of ratings will simplify the calculation for the guys in the field, which is always a good thing since it helps eliminate confusion and mistakes.
