hey everyone i am building an ls/vtec motor with wiesco 12-1 compression pistons, ls crank and b16 head. i just installed the rods,bearings,pistons,rings,etc. i just checked my piston to block height(at TDC) with a depth guage and it is in between .017-.021 in all 4 cylinders and i need to know if that is the right height? any help is appreciated!

when in doubt clay the cylinders and put tthe head on and roll the motor over by hand. pull it apart and see if any damage occured

Claying should always be done on a new motor just to be sure. Make sure you lock the vtec lobes in as well when you clay.


I recently built one though that was .007 in the hole, 12.5:1 mahle's, .010 taken off a PR3 head and using skunk 2 S2 cams with a .030 head gasket so I am sure you will be fine but casting variances and valve relief differences mean you should clay just to be sure. It will take an extra 2 hours of time for the peace of mind.

i forgot to add that i also have golden eagle head gasket... i called wiesco and they said that they PTD was good as long as i have a .030 head gasket.
