My tuner that installed my cams, retainers & springs didn't recommend Head bolts even though I peak at a slight tick under 25 PSI, now I have been talking to another tuner here locally and he highly recommends getting them done. He did however say that all tuners are different and have different taste of tuning. He says I'm on the rather high side of the spectrum for his liking and that he would definitely do the Head Bolts for piece of mind.

My evo bothers what do you think?

 

wrong forum man




but while i'm in here, you may not NEED headstuds right now but they cant hurt. If your tune is good, you'll probably never pop a HG, but a little bit of detonation coupled with substantial boost can blow it. I'd run a peak of 23 psi if you want to stay on the safe side and/or just get a set and throw them in. I have them in stock at 95$ shipped BTW,

 

I'm lost , sorry fellas.

 

Go to the Evo VIII/IX forums and do a search. Lot's of Q and A on the topic there.

 

Get the head studs man...
