I'm 20 over with my b16-T, didn't have to modify anything. Using stock OEM.

20 over is fine for the oem size.

think about it... in the honda service manual they sometimes recommend a slight bore on the cylinders with over sized oem pistons. everything in the book is oem and they dont make an oversized headgasket last time i checked....just to make u feel better

Cool, thanks for the info.

Another question>> i have 10.6:1 JE pistons, should i get 9.0:1 pistons or use a thicker gasket to lower the CR? I will be using the VAFC hack with this also.

Re: (GS-Rcivic)

Personally I would drop it down via pistons but it's really up to you... I however would NOT change your C/R with a headgasket (leave that up to pistons and pistons alone) but that's also just me... Just my $0.02
