Currently I'm building my bottom end pretty much bulletproof. I however haven't done a single thing to the head. I'm not going to be revving past the 7500 redline h22's have. So am I safe running this? I'm trying to run 400-450whp on my car. I will build the head in the near future when the funds become available but at the time being, can I run a stock head without the possibility of having a valve float on my h22?

I really rather spend my current funds for the rest of my turbo setup. Please help guys.

 

Not that I'd recommend it, but I've taken a completely stock head as high as 8400 rpm. I took it to 8000 rpm pretty regularly. This was on ~25psi. It wet a bunch of 10.50-10.60's in the low-130's mph on the stock head.
