Yea I wouldnt run them. Compression will be to high to run anything more then 6 or 7 psi. Your better off going with 317 heads because they'll drop compression from 10.1-1 to 9.6ish-1

How much boost are you trying to run? If you are planning on running less then 10 I would say run the 5.3s as you will make more power at less boost. Anything over 10psi I'd suggest going with the lower compression 317s. Good luck and run meth for sure!
