Considering that very little has been done over the years to reduce costs in Pro Stock, and considering the cost, time of development, and the politics that goes into the cylinder head side, why would a spec head be such a bad thing for NHRA Pro Stock? Each OEM manufacturer (and OEM only), whether it be Ford, GM, Dodge, or Toyota, just like in other VERY POPULAR motorsports, provide an NHRA approved serviceable race ready spec head with an NHRA logo etched all throughout the intake and exhaust ports? Buy it, install your valve springs, retainers, and valvetrain, bolt it on, and race it? Just think if you could buy a spec set of Pro Stock heads for under $5000 brand new from the manufacturer. NHRA would be allowed to check the heads using stencils, go/no-go tooling, height parameters, volume testing, etc. No machining, grinding, welding, blasting, or etching allowed. Just a service limit on flat milling. As would be expected, each manufacturer must meet a valve size, port and combustion chamber volume, runner height, valve angle, and valve length spec. It seems like NHRA has done a good job thus far in Pro Stock in keeping things competitive between the manufacturers as far as the approved cylinder head castings is concerned. Would this bring more people either into or back into the class? Would this help the race engine shop economy since more engine shops could cater to pro stock, rather than the small handful that currently do now? If you currently develop winning pro stock engines, then could you still develop winning pro stock engines with this mandate? How would this not cut the engine (or providing) costs of NHRA Pro Stock in half? How would this not result in more participation from the OEM manufacturers and ultimately more corporate sponsoring of the class? How would this make the class less competitive? How do the negatives out-weigh the positives?
