i just got my b16a running i built the block after i boosted it and blew it i put new eagle rods, arias pistons.eagle block guard and rebuilt the bottom end and now that it is running it tics real bad and it smokes out of the valve cover i have alot or pressure in the vavle case and i think that the head may be messed up like bent valves or some thing oh do arias pistons move in the block a little bit

 

do you mean you can move the piston with rings around in the block? i would say no cause i see that as blowby and lost power. and very low compression. my 2 cents

 

ya i want to lower the comp with those pistons there 8 to 1 supposedly
