There is no doubt that allowing ported heads in stock will increase the cost to build the heads and engine.In super stock a good set of heads and intake cost around 8 to 10 grand. The issue with the CC size of the ports. If you use the SS volumes they are quite a bit larger than an actual stock port. The heads that I run have a intake runner volumn of 165 cc. The largest stock head that I have poured personally is about 157 CC. So you can see that if you use the SS head volumns the heads will be much larger than a stock head. Ported heads would not be a good idea for stock in my opinion.The move should be toward a more stock head. Even a rookie tech man should be able to detect heads that have been acid etched and shot blasted.
