But remember you need more spring pressure on the intake side to help keep the intake valve in check because of the intake pressure and the exhaust valve opens against alot more cylinder pressure transfering that pressure right to the rocker arm.

I agree with your opinion Brian, the pressure's in a blown engine are much different than a N/A engine. That's why the question. If I have to go to a different rocker I would like to know before hand. I know one thing for sure with this blown engine build. It is much different than what I am used to and the learning curve is steep.
