Serious brain fart!!! Could it work??? Yall tell me!!!

the problem with the slant six would be head gasket issues ,all the diesels I work on have 6 to 8 head bolts sealing the the gasket ,most older diesels had 22 to 1 compression newer engines have 14 to 1 ratios and make up the power with turbos,this is why the newer engines need glow plugs,intake heaters, to start now the NASCAR block with the 6 head bolts could be a start.
