getting ready to finish my block and wanting to know where to pick up 1/2'' headstuds for my k20. Are they really worth the extra work to have them done. Anyone with experience on them with either k's or b's?
Why is that the most common response? What's the most boost, timing, rpm you've ever run? What's the biggest compressor, nitrous shot, bore you've run? Is that on a K-series?Why? Unless you are planning on copious amounts of boost(NASA levels) there is absolutely no need to use more than the stock size ARP head studs.
Maybe I do ,I thought he meant the ge or arp with the stock thread pitch..You do realize the 1/2" studs in question require the block and possibly the head to be machined with new inserts right? The stanard GE and ARP type studs with stock thread pitch are not 1/2" studs. Maybe 1/2" 12pt nuts. The 1/2" studs use a 9/16" nut I think...Maybe you need to research the products you sell to be more informative.
where r u located?I hate driving down to Olsen engines to bore me blocks..You will have to contact ARP and see what they have in stock that would match for length, and then take the block, head and head gasket to have them relieved for the larger stud and then drill and tap the block.
Can it be done, sure it can, but again why?
The Cost alone at the machine shop, could be spent far wiser on other components.
And yes I do own a machine shop and know what I am talking about.
if you want to figure out if 1/2 studs are really worth the trouble then you can do a simple mechanical analysis to compare 1/2 and the standard. find the expected combustion chamber pressure your motor will experience and the rest is easy. material properties can be found from the manufacturer. there is probably a factor of safety also so be sure to incorporate that. if the force does not stud does not exceed the tensile strength of the stud then you are good to go. if you want to go even further you can trying calculating a size that never reaches its endurance limit. good luck.getting ready to finish my block and wanting to know where to pick up 1/2'' headstuds for my k20.
