The 2014+ C7 Corvette Stingray, 2017+ C7 Corvette Grand Sport, and 2016+ 6th gen Camaro SS out of the box has some very high flowing heads with approximately 295 cfm. For some of us, this is just isn’t enough. We need more flow, a more aggressive cam, and want to see nearly 600 naturally aspirated rear wheel HP! Want to go boosted? Our hybrid head port drops the compression ratio for boost now, or later and we’ve made nearly 600whp with these and our cam kit on an E85 LT1 car!
Here’s what we do! Fully CNC ported intake and exhaust ports, custom intake valve job, custom full radius exhaust valve job, intake and exhaust bowl blending, optional milling for increased compression ratio.
Stage 1 is CNC only
Stage 2 is the trend for boosted engines with smaller ports for higher airflow velocity
Stage 3 is the fully ported windows and all
