Can not stop oil from leaking.

Yea no gaskets front and rear....Have you ever used the stuff from permatex, called THE RIGHT STUFF....all the parts houses carry it...it is the best...cost 15.00 a tube sets up in 15 min's....Make sure you are ready to use it....Also...Are you using a torque sequence and proper torque specs right?????Also liquid thread sealer on all bolts for the intake...oil/coolant will seep up bolts....also front and rear on the block I have seen little alignment tabs /roll pins, make sure your intake has holes for these or it will not torque down properly
