I would like to know what type of power gain you can get with these heads paired with the Ford Racing Boss 302R cam shafts - Exhaust Cam 13mm Lift 290 Duration & Intake Cam 13mm Lift 263 Duration?
The Boss 302R intake cam shafts with 13mm lift say the can be used with these heads but why dose the cylinder head say it can support 12mm intake?
Which would be the best Rocker Arms and Lash Adjusters to use with this set up?
Thank You for your time and knowledge,
