lyonroad has a beter aproach,as unless the block is sitting on bell end ,the weight of the front cover will be easey to manage. the seal is not a good centering gauge. i grind the sholder of the front cover seal stop so seal can be changed with out removal of cover,and when instaling cover a sleev that rests on seal machined aria would alighn the cover true to crank. idealy get front coverstop machined true to seal aria,tho the next isue becomes geting the seal in strait.
