Doesn't Stage V Engineering make Hemi conversion heads to use on a wedge block? I understand there is way more to it than that, but they are out there, right?



Yes they do , not very often but they do , it is not just a drop on and go though. You do need to still grind on the block for pushrod clearance, and you have to add oil drains to the pan. The upper row of head bolts is in the intake, this may actually be better than the valley studs? Then you need hemi pistons, that are a custom because the 440 is a .070 over hemi size not, including any overbore the 440 needs .

The hemi blocks aren't that expensive anymore to make using the conversion heads a viable option unless you have thousands of dollars into a 440 block in upgrade machining ...
