i have a crx with b16a swap, and i plan on swapping the bottom end to gsr. becuz i getting one pretty cheap. well, i plan on boosting the engine at one point but it be later on. i did some cr caculator, and it show 9.8 cr, but i can use 2 layer gasket and bring my cr back to 10.1(becuz i would have to drive this setup for at least about a year, so i want as much power i can get out of it right now), i plan on getting some comectic gasket, and arp head stud, so when i ready to boost it then i can get just oem style comectic and put it back in. so... what is the size for 2layer gasket? thx

 

i found cometic can make custom gasket, instead the 2 layer oem gasket trick, but thanks
