opening the ports too much will reduce velocity right, so maybe just remove harsh obstacles from the casting process and polish them up for even higher velocity potential. If anyone has a extra head laying around I would be willing to pay for shipping and possible trade. I have a new atx solenoid pack and a new TSS sensor and a used atx ecu that I would be willing to trade for a spare head. I also have a used MAF meter that is in unknown condition that I could throw in. email me or send a private message and keep the suggestions about the port and polish coming. Thanks
