[need help]

This is my first Aluminum block (World) and aluminum heads, 572RB with 572-13s. I torqued all fasteners with suggested values and using both Inch and pound tools both calibrated........recently. Only second use since getting them back. Question is cold vs hot values ?? and retorquing needed? cylinder heads are studded for VCs & oil pan (aluminum) all have flat straight rails. still small leaks at various areas. Used quality gaskets I feel ? After first start-up, several fasteners could nearly be turned 1 full round?? looking for suggestions and hints , thanks
