250cfm + exhaust flow out of a 799 LS cathedral port with a stock 1.55” and stock valve job .!

Should we match exhaust to header size or leave the step out for reversion ?

If n/a or turbos no ., if it’s a blower/nitrous car yes … that’s what I do anyways

​@georges8secpony I ported some 317 heads and made a video basically just did everything you are doing to these and then milled them .020 deshrouded valves a little smooth the chambers , added some 4cc dome pistons and a cam 2800 stall in my 02 Escalade lq9.. might put some 1.8 rockers on it to get lift up closer to .600
