If they are 150/160 on the seat as posted they "should" be ok at 7psi with your cam. I'd still pull a valve cover and test the spring pressure to insure it is 150....easy insurance.
I ran the BP7EFS plugs at 0.32 at 18psi at 6700rpm without any problems. Time to spin some wrenches.

spoke brian tooley today and he too agrres tht the seat is good enough for messly 7.5psi...
tiago heading to the dyno saturday...will reinstall stock lenght and placemnt to test...gotta thouble shoot that varaible.
in fact, i was on 7 cylinders for the majority of the year this year, right from the start. my butt dyno was failing me, i thought i just got used to the power, lol.
i bet thats a relief though!
