BSwope and I have been chewing on this for awhile. Higher torque factory head bolts. What HP are they good to? Standard ARP head STUDS vs 625's.
At what point are the 625's better than the std ARP head studs with a 190,000 PSI rating? We would like to have opinions as to the FACTS, not that someone bought them because they are the BULLETPROOF way to go..
Thanks guys!!

 

Anyone?????????????

Why dose Keating run stock head bolts .vs studs??

 

Big Swole on compd just made 766 with stock head bolts torqued to 160 and 12v o-ring head. Still tweaking tunes.

12v guys have been doing this also

 

I though he had stock head bolts but wasn't sure!

Yea hes our offical tester

 

Im keeping this one going...

 

If you can have Jeff do them than I would say go for it. Hes been using head bolts in lots of big HP trucks, but he knows what hes doing. To me its not worth $400 to break a bolt off in the head. My luck it would be way back on cyl #6. ARP 2000 and mls gaskets are good to atleast 800 hp maybe more. So it just depends on how far your going to take it.

 

x2 Jeff Garmon has some magic up his sleeves and makes stock head bolts work in rediclious applications, but I wouldnt chance it.
