Did this thread ever get to a consensus as to which heads that fit a stock block flow the most air? Only asking because I'm waiting on Victors to come in stock and wondered how they rated here and if anyone has bought them and flowed a set?
I think, AFAIK, they all fit and work on the stock block. All the W heads do. The Victor and Indy heads are the top of the heap aftermarket head and they work on stock block.
