you dont need them, but you should get them anyways.

i didnt need my twin disc exedy clutch to make 400, but it is worth it also. be safe and do it correctly

 

I disagree. Why bother if its not needed yet? Its more money and more time spent, and if its not done correctly is more money and less time you are able to drive the car.

Don't replace its if its not broken or can do its job as is.

 

thats how i kinda feel

 

Thats the truth, My goal is to make 350 awhp and 350 awtq (just rough figures) and its a 100 percent daily driven. the car has 36k miles and I just cant see spending that money on something thats going to put my car out of commission for a week. Its senseless.

 

^ I'm looking at the same HP figure. Anyone else chime in with new info?

 

im currently at 330whp, 328 tq at 26 psi on a mustang dyno and stock head bolts. mine have been holding fine now for over 30k miles but im still going to endup doing them soon just for insurance. theres also a big thread on here somewhere about doing them 1x1 and pulling the head to do them and some people swear the 1x1 method works but personally im pulling my head.

 

almost every stock block car i tune has stock head bolts.. there's your answer.
