What upgrades would I need to run ported stock heads with my current combo which consists of blue tops, TA 49, and stock cam. My goal is to run high elevens to low twelves on pump gas and alcohol. I've run a 12.8 at 109 with my current set up at 4900 feet. I know traction is big issue which I plan on addressing. Can I run the ported heads with blue tops and the stock cam or would I need to upgrade both. I've done a search and there seems to be some mixed opinions out there. Thanks
