I know Hughes was having problems getting help in the shop recently.
I don’t see the BM listed currently on the list of cylinder head options there.
I wonder if they’re actually available.
And if so, how much.
The non-BM cnc porting option from them is just over $1700.
That’s puts the cnc’d non-BM heads at over $3600, plus the cost of the spring/retainer/lock upgrades needed for the 550+hp cam.
Of course, you don’t need 300cfm heads to make solidly over 550hp.
