i plan on running a b20vtec and i read a post that said if i run the rs machine type r replica for a b20..i can use any size cam without having any problems with valve to pistons contact..due to the pistons modified valve relief..b16 head by the way..can anyone give me any information about this..or point me in the right direction so i can get an answer...thanks

 

clay the head if your going to use "aggressive" cams in that b20. thats my stand on it

 

yes sir... dyno prooben

 

I ran a set of skunk2 pro 1 on these pistons no problem

 

thanks...do u know if i can run skunk2 stge2 cam on a stock b20b block

 

i dont think its a good idea.. but i had tha stage 2s with my 84.5 rs

 

You should always clay the valve relieves, and meshure the clearences with vtec rocker locked....
whenever you assemble a engine with diffrent parts(other than stock)

Never assume that it will be okay. "Meashure"
Also remember to meashure valve to valve clearences.

 

well i have je 12.1 compression pistons..will i have a clearance issues with stage 2s with these

 

the pro 1 are rated then just stage2! if you are willing have a machine shop mill the pockets back some

 

Probably not, allmost all piston mfg oversize the valvepockets on their pistons.
BUT you should def meashure clearances.

If you have oversized valves make shure your clearences(Valve to valve) is within specs with these cams.
