b16a pistons

[Beauchemin]

Ok so i was told that the jdm P30 pistons wont work with the Ls build becasue the values would hit the piston...
Now anybody know if thats true or should the p30's be ok to put in??

they should be fine. pr4 pistons can hit the valves with a vtec head because the valve reliefs are shallow compared to the vtec units
