There are part numbers floating around for a pieced together set that you can run. I think the last time I priced it out it was about 200 for the studs, nuts, and washers. Only issue is you have to have the nuts machined down to clear the cam caps.
If there was a set available for that price that was ready to run I would be in line even if I didnt actually need them. Peace of mind is priceless in my book. However, I have seen the pd150 bolts hold quite well in most situations and for 70 bux its a darn good deal.
