I've used stud pullers before, but it's just as easy to stack washers and use the nut to pull the studs out.Better yet, just have the machinist pull them out. He can then spot face the heads for the guide plates then tap the holes. ------------------

if i want to spend the $250 per head that the one shop quoted me that didn't know if they had done it before 
Called 3 other smaller shops around town and they said they didn't have the tools  I figure if i could pull them getting them to tap the holes would be cheaper, and or any shop should be able to do that no problem. When do you have to install guideplates? Any time you convert to screw in studs or what's the deal? and do you need to mill the bosses flat even if you don't install the guideplates? also would this tool actually line it up allright to tap the holes yourself? i would imagine it would be best left to professionals, but just wondering [This message has been edited by Dubz (edited 12-13-2004).]

Let me back up then. Why are you pulling the studs? Usually the only reason is when someone wants to install guide plates. Is it to just install threaded studs?------------------

yes, due to the positive stop nature of the 74 era press in studs, i'd prefer threaded studs that will not pull out and will allow for valvetrain adjustment without having to get the comp rocker arm adjusting kit, which won't really solve my problem if the studs are pulling out (as they are not level when a straight edge is layed across them) it appears that the tool may be only for a sbc however, unless the studs have the same spacing which is doubtful This week i'm gonna try to get some Stover Lock nuts that are heat treated like are in the comp kit. Probably only be able to buy them in boxes of 50 or something stupid *grumble* Anwyay i'll just use some grade 8 washers to space them, and then the rockers should hold thier adjustment so i should be able to tell if the studs are actually pulling out or if they were just not all a uniform length.
