ARP headstud questions....
I did the same as you. Had regular headstuds when i did cams never had to re tq them. When i went with the new build i just did L19s
I wouldent worry about the rods if your tune is on point no worrys there they will be fine for this build it sounds like just something to think about if you are planning for 700+hp atleast buy new arp they are cheap.
L 19 are backordered and I just couldn't wait so I just placed an order for a new set of standard ARP headstuds...AMS/Headgames w/Kelford 280's on the HTA 3582r and E85 should make some NICE power!!!
I agree with you...my tune is conservative as far as timing and A/F's as I want longevity over pure peak power etc. I love E85 and how much power you can make with it!!
if i remember correctly, i read somewhere that TTP said they use the regular ARP studs to 42psi. don't quote me on it and don't get mad if im wrong lol.
also why would you want to know if you can re-use them and someone had said they retorqued them twice...should i be doing this retorquing with mine??

you could have re-used the stud, you have to check for stretch. There is tons of info about it if you google how to measure it. That is what would tell you if it is ok to re-use, because once they stretch there no good. And you certainly don't need a L19...we were making 1000whp in mitsu's before L19 was even thought about, and no problems with stock headgaskets and no o'ring.
Congrats on your new purchase!

thx, someone on these forums was selling one of your/AMS evo race heads for an unbelieveable price so I had to jump on it....I'm having it hot-tanked, decked and pressure checked and then it's going on w/the Kelford 280's. I'm anxious to see how much more hp this combo is going to make over my stock head and GSC 272's (GSC very early version of the S2's)
if your getting work done to it, and have not taken it anywhere yet, you should consider sending it to us for a update...we have a SICK valve job update that would help that puppy scream!
your going to see at least 60-70whp

send me a pm on what the specifics are. I'm sending it to the local machine shop that built my 2.0 shortblock (they are very familiar with evos...Machine World is the name) I would like to send the head to you guys to verify that it is indeed a head done by you(if that's possible) and I'd like you guys to stamp or mark the outside so it's visible for all to see. Let me know, thanks!!

I just read up on these on ARP's website and they do appear to be a little bit stronger and will seal better/stronger do to the "undercutting"
