AFR heads are great.You have 300 CFM potential.Look at the 2 cams I posted ,similar by the numbers,but the solid appears to have a higher RPM range,,, there are reasons.
Why do you want to use a hydraulic?
note in the video the builder states that his carb is good for 20 more horse power when it could say use this carb with "these" parts?
you might consider 220 AFR heads?
I stepped up to AFR 227s
If you want to street drive this "550" HP engine,then consider a 434?
