The baseline pulls will be with an established stock type non-lump head. Then a head change with the same type head(same chamber cc's and valve sizes) with lumps installed will be tested next. This will be a more apples to apples comparison, and show the true gains that are available from taking a stock head and what increases are there when you put in lumps, with everything else remaining the same. Then the cam changes and more aggressive head combos will be done afterward. Having an engine dyno as opposed to a chassis dyno will greatly help speed up parts changing hopefully.
