Hey. I've heard that LS/VTEC conversions have low piston to valve clearances but can be (partially?) remedied by "grinding the piston's valve reliefs with a die grinder with carbide burrs and polishing the result with cartridge rolls" (hondatuningmagazine.com).
Assuming all parts are stock, does this mean it is pretty much pointless to shave the head? Are there any other ways to increase the clearance ie. aftermarket parts/headwork? Will any of these have an unwanted effect on compression?
When does the low clearance become a problem? With what mods? Or at what rpm?
