351w build Any thoughts on performance??

I have a 351w I have put together and wanted some ideas on what the performance might be.. I have my guess but wanted to see what others think.

74 351w .060 over stock dish pistons
C60E heads 54cc fully ported, 1.94/1.6 valves, screw in studs, guide plates, roller tip rockers decks cut .030
cam specs are solid flat tappet 238/248 @.050 512/536 lift 112 lobe seperation
port matched Victor Jr intake.
900 cfm ProFuel carb

I know the heads aren't optimal for the 351 at all but I had built them for a 11.1 289 build that old man winter claimed the block so I used what I had.

Any and all opinions are welcome

.. Looks like about 350 HP... limited by the heads... did you ever get it done?

.. I have a 351W in my boat. World/Dart WindsorSr. 195cc heads, KB pistons, Crane cam, VictorJr. intake, Holley 750...
