Hey Wes-with all the head companies out there,a direct answer is when you price shop and then expect to get something for nothing,this situation isn't any different than anything else you buy where you get what you pay for.

One certain fact is the lower dollar head companies DO NOT have the R&D programs that you pay of in the price in the bigger brand name companies.

The days of a neanderthal caveman with a die grinder thinking he can match yrs of flow-bench research and CNC porting is just a silly notion.For one thing to match port to port and let alone head is head with a die grinder the percentage isn't in favor of hand porting.

If you choose a BBC,you should do so understanding and accepting the heads are going to cost you alot more than a SBC.
