While the price for these headstuds might seem crazy, they can actually present a better value than the 1/2 stud package. In addition to having a higher clamp load rating than the 1/2 studs, the H11 units can be more cost effective than having to purchase the 1/2 studs plus having your block machined plus having your head machined + plus buying a custom headgasket. Thats not to mention the down time you save by not having to send all of your stuff out to the machine shop and we all know that time is money!
The H11 stock dimension head studs have approximately 21% higher clamp load rating than the standard headstuds for the 2JZ and approximately 4% higher clamp load rating than even the mighty 1/2 headstuds.
