When is it necessary to replace your headstuds? I heard when you are running over 300 hp and someone else said when you run over 350 hp???? Thanks.

 

anyone?

 

arp headstuds are cheap insurance

 

arp only recommends using there studs for a total of 3 cycles, (build, tare-down, build...) for stock studs i wouldn't push them past 2 cycles. as far as cylinder pressures, the stock pieces that were selected by the manufacture probably have a little headroom on them over stock output, but who knows how much? like nickG said, for how cheap they are you might just want to pick them up and not have to worry about it. It also looks good on your spec list!

 

ya, arp or aebs

 

I heard any time you take that head off the block. It's good insurance...
