ALERT!! SOUND THE ALARM!!..

Is that the shipping date Summit gave you on the heads or straight from ProMaxx. Summit is known for giving a far out shipping date on stuff they don’t have in stock so people don’t call everyday. Then they are happily surprised when they show up early

That was the date on the ProMaxx site. The SBM heads have all been out of stock for several months. Must be expecting a shipment.

He quoted me $800 to convert my regular 171's to the CNC Shocker 185 level with 2.08 intake valves. That seems pretty reasonable, but I can't use that flow at the moment. Going to give it some serious thought when/if a 4" crank goes in, down the road.
