- VAC always recommends High Performance Valve Springs even with mild camshaft upgrades. This ensures our customers always get the best performance and reliability from their engine by preventing pistons-to-valve contact in the event of an over-rev or mis-shift. - All camshafts must be installed by a professional, who can check piston to valve, and valve seal clearances. - All M20 cams should be installed with fresh Rocker Arms; premature wear of camshaft lobes is likely to occur otherwise.
