Vortec's - How to Kill Flow and How to Increase it! Vortec Head Exhaust Flow

Theres alot of talk and questions about exhaust flow on Vortec heads. Hopefully this video helps answer some of those questions and provides some answers on how to increase flow when home porting your Vortec exhaust ports. *Watch in HD 1080 to see charts easier* Heads flowed at 28hg, 4.030 bore with *No Pipe* This video is educational (not a how to port video) and I can only provide information and results from my own experiences and flow tests. I am not responsible for any damage from others trying to port their own cylinder heads. Please comment below if you have any questions Please don't forget to like and Subscribe
