I have been searching the internet, with absolutely no luck, for information about World Products Torquer cylinder heads. I recently bought a slightly used set of these, and since I am away at college, I have yet to see them. They were bought with no rocker studs, and I can not get a definite answer as to what size they are. I was told that they were 3/8", top and bottom, but I can find no manufacturers (ARP, Crane, Mr. Gasket, etc.)who have anything but studs with a 3/8" top, 7/16"-14 bottom. Does anyone know what these heads require. (On a side note, why does ARP not recommend using stock crimped style rocker arm nuts with their studs?) I wanted to know so I could order the parts ahead of time, so I can install the heads this weekend when I go home. Also, the instruction on World Products website recommend head bolt washers. I have a set of fairly new (have been torqued once) of grade 8 headbolts, and figured I would use those. Can washers be used with these, or do I need special bolts for the washers? If anyone out there knows anything about these, I would appreciate the advice. Thanks for your help, Dan

Re: Cylinder Heads
i have never seen any 3/8" X 3/8" rocker studs. using crimped nut with screw in studs could cause you to unscrew the stud when adjusting the valves. i have seen this happen on BB chevy. -
Re: Cylinder Heads
Thanks Clem, do you have any ideas as to why World Products would recommend head bolt washers. Thanks again, DanComment

Re: Cylinder Heads
you always use washers with aluminum heads,and you can use them with C.I. but you need to check the length of the head bolts because you loose 1/8" of thread engagement using the washers. if you use stock GM bolts i would say you do not need washers but with after market ones check to see if they have a washer type head to prevent the hex from digging into the head. most after market head bolts are longer to be used with washers.Comment
