I am in the process of building up my 5.3 block from the bare block up. So far I have been able to get all the parts I need, except for trouble with gaskets. Does anyone know where to get a complete engine gasket set for this engine, or will a complete set from a 5.7 work? I wouldnt think it would because of the differences in bore size. Thanks

while you got it out why dont you bore it out to the 6.0 and use the 5.3 heads if you already got them.

I know the 4.8 gaskets will work because the bore is the same on the 5.3 and 4.8
