I am running .5mm oversized flattop valves in my PnP'd B16a2 head, it has aftermarket valve springs and retainers in it with itr cams. I am runnning a stock B16a2 block. with the dome on the stock b16a2 pistons will i have a clearance problem with the oversized valves?

 

valve to piston ?

 

yes valve to piston? i don't want to start it up and bend the valves

 

clay the engine before initial startup and check your clearances

 

Man, if your asking Honda Tech members to tell you if your internal clearances are good or not....I'm gonna say your in for some problems.

The valve reliefs are cut into the piston for stock diameter valves....do they have extra? Only way to know is to clay it man...do it the right way. If you do, then the day you start that motor up, you KNOW it's good. Don't forget to manually engage vtec when you clay it
