hi...i have a AEBS sleeved 84mm bore GSR block...GSR head...i ordered my pistons from race engineering and asked for a gsr 9:1 84mm bore piston...i recieved a B20B 84mm piston for b16 head it says 9:1 and the guy at raceeng said a b18 head would drop it to 8.8:1 ....i was just wondering if this is going to work and is ok...part # for the pistons i got is JE-185917 if that helps...thanks in advance

 

no prob now...no replies but talked to race engineering and figured it all out
