may sound a tard but i really dont know lol
does the dispak bolt up the same? differences from the GM to the cos head, is the coscast one just not prone to going porous?

Coscast heads can still go porous, there is just less chance.

i have thought of this.. was just going to send my head off to motorcast for everything to be changed and reset, but was told the coscast head can cope with more power? or is that a load of bull?

I remember seeing some info a while a back that gave the tensile strength of all the different variants of heads that were cast throughout the XE and LET production life. I remember some of the GM ones from KS in Germany were crap. The early coscasts were a much better casting.
