Question Should I be OK with my 918s for the time being? *9psi and 6.0L heads*

I just found out that I dont have to smog my car afterall, which is why Ive been waiting on installing my D1SC.

Anyways.. while I was waiting I aquired a set of 6.0L heads from a friend.. and had plans on using a Patriot dual spring set on my the 6.0L heads. Thing is my house was broken into recently, and they stole my 60# Mototrons , didnt even have them for 24hrs and they probably didnt even know what was in the box they were in when they grabbed it , so the money I was going to use for the springs now has to go towards another set of 60#ers. I dont have the cash right now for both.

My question... I currently have a set of 918s on my stock heads.. and have ran them for about 4K miles. They were originally used on my TR224/114 cam and were raced on about a couple dozen times at the track. About 1K of those miles was after installing my custom grind blower cam with .580 lift, never raced on this cam, just mainly cruising until the blower was to go on.

Should I be worried about using these 918s on my 6.0L heads with about 9psi? After a few thousand miles are they going to be too fatigued to use on the new cam and boost? Or should I ultimately wait until I have $ for the Patriot Duals?

THANKS IN ADANCE.

They should be ok till 6000-6500rpm and under 600rwhp. Check the seat and open pressures on them. If they are good I would run them.

I have been running 915's for years, so far so good.

918's are stronger so I would think you should be just fine.
