Aftermarket/Replacement Cylinder Head Rule Change

PJ305 · 12-22-2017, 11:02 AM

I have done research on SBC replacement heads and Dart should be the only one approved for Stock. If NHRA is looking here you go.
"DART" WISSOTA #30424361 or #10024361 bare casting plain and simple.I don't believe replacement heads are needed and why would you allow so many with totally out of whack specs. This head is the only one close to Stock, it is cast iron and is very close to your aftermarket specs.If you ever do teardowns you can police one head easier than 8 different ones! Yeah and by the way why isn't it on the list?
