As for the work done I find it hard to believe that some of the other tuners are not taking the heads off to prep them. You generally find increased power in the upper RPM range if you go over the heads. Here’s what we do on the heads.
Opened the throats on both intake and exhaust.
Bowls and short turn about 100 thousands opened.
Full length on the exhaust runner opened.
New custom springs and retainers.
Flow went from 360 stock to about 397 on the intake.
Flow went from 224 stock to about 260 on the exhaust.
Flow numbers kept going up above the 600 lift mark vs. dropping on the stock head
Head work done, Custom cam, Custom Springs, Custom Retainers,
If you do not do the heads like some of the other tuners power levels off and drops above 6200 rpm where in our case the power continued to rise to 7000 rpm.
Your Factory heads are required for all the work.
Requires stage 2B package.
