if you plan to yank the heads id swap the pistons right away, get a set of flat tops to bring the compression down to about 8:1. and if you are any good with that 3d cad you are much better off going with the TT setup as the big difference between the two with regards to difficulty is designing and fabrication the tubing and headers for the turbos. , secondly, and i really think this is a big point, your engine will deliver 150-200 more shaft horsepower with a properly sized turbo setup than with a crank driven supercharger at the SAME boost level, simply because of the SHP needed to drive the SC. also boost is adjustable... so tour wife or 17 year old son isnt handed the keys to an 1100 hp pickup with no rear grip..
