I hear porting heads is not good with boost.. but what about flow matching? I have a decent sized cam but want to make sure i am getting all i can outta it with a lil head work to help..

 

Some porting will help intensify the powerband. The 5.3l heads will respond to some mild port work in the valve bowl area and installing larger valves. We have a Stage 1 port package that runs $705.00 per pair and includes all necessary cleaning and machine work as well as new stainless steel oversize valves.
