Setup for 273

interesting Point but there are heads like the 2843675 ones which were on Both Engines 273 and 418. the bore diameter is only about 7mm more.also the valve diameterdiameter is the Same. only 340 up has bigger ones.

there Are no adj Rockets on my 273 heads because someone Changed to hydraulic lifters.

with the new cam i want to Chance back to solid lifters
