Custom made RC-30 replacement head bolts. These bolts are made by ARP, one of the top motorsports bolt manufacturers in the world. They are made from their 8740 Chrome Molly material, which has an Ultimate Tensile Strength of 200,000psi. In addition to being custom made for G-Force Engine Development to mimic the exact fitment of the OEM bolt, these bolts will incorporate a Torx T40 head, instead of the 6mm Allen head of the original bolts that are so notorious for stripping out. Torx ("hexalobular") designs allow for far more torque to be applied before they strip. In addition to the Torx design being stronger, ARP's "heading" process will also provide for some additional strength. These should be the last head bolts you will ever have to buy for your RC-30.
I only need 3 bolts to finish an engine for a customer. However, with the fact that nobody in the world (quite literally) has been able to source any, I am forced to get some made by ARP. Now, I could pay $58/bolt, and order 48 bolts at that price to get the three I need. But, I doubt anyone else would want to buy the others at that price. Or, I can order 480 bolts, to make the price $25/bolt, or $400 per engine set. Although this is still not the OEM price, and you would have to buy complete sets (for two reasons stated below), these will be the only head bolts available in the world, now, or EVER AGAIN, for the RC-30. Now that I have been able to get the price down, how many people would be seriously interested?
Why full engine sets?
The head bolts are made of different materials, with different torsional and clamping properties. Not replacing every bolt will lead to uneven head torquing (clamping pressures).
With the different head types (6mm Allen vs. Torx T40), the torque loads applied to each bolt will be different. Effectively adding to the problem in #1.
Also, switching tools back and forth is never fun
