1100 turbo head studs?

How much hp and or boost can the stock ones take? Tks

If I recall correctly, most tuner companies claimed 215-220 hp was the ceiling for the stock bolts. Personally, it is cheap insurance to run studs

Lots of big boosted guys on HardcoreSledder say up to 300. I have been running 260 for years without a hiccup. Your personal results may vary...lol
