340 head, intake advice please
915s are "J" heads, and came in both 1.88 and 2.02 intake valve sizes. Considered to be one of the better LA heads.
Screw it together and run it.
Of more concern is the fact that the '73 340 was a cast-crank motor; and whether your rebuild retains the cast crank. It's an adequate crank, but it is externally balanced and requires a 340 cast crank only flywheel or convertor/flexplate for proper balance. Note: this external balance is NOT the same as an LA 360 or 5.9 Magnum. generally, if it retains the cast crank/external balance, it will have a harmonic balancer like this:
If this is what it has, it MUST be assembled with the proper parts; the specific cast crank flywheel, or the 340 external balance torque convertor/or a neutral balance torque convertor and the B&M 10235 flexplate (727 trans.) which is made with the 340 external balance.
