when building a CR/Vtec or LS/Vtec, can the stock internals (pistons, just everything) be used?

You might have to open up the valve reliefs on the pistons, since they weren't meant for the larger VTEC valves.

odds are you wont have a problem, i know someone who ran toda c's on a stock b20vtec, never had to touch the pistons.

if you are worried, http://www.c-speedracing.com has a how-to on how to clay your clearances.
