Well... I'm definately ordering from them now due to this reply, It shows that they really know what they're talking about, maybe the first reply was a secratary like mentioned above.
Here's they're reply
Ok, I see what you are looking for, the GSR studs are normally included but we can also send the B16 if you like. What you mention is a common misconception...usually found on the web forums...Honestly it will not make a bit of difference in terms of stripping. Both the GSR and B16 studs have the same exact amount of thread that screws into the block. The difference is that the shank on the GSR is 0.150" longer than the B16. The B16 is 7.100" overall and the GSR is 7.250 overall. If you are having the head and block milled, or are using a single layer gasket, we recommend the B16...you end up with the thread flush with the top of the nut. If the block and head will not be milled, the GSR sits just about the same way, maybe a thread or two above. Hope that helps.
