906 big block valve ?

dodge71demon said

Is it possible to use oversized 2.11 intake valves in a 906 head without hitting the flat top pistons on a untouched 383 HP motor? Real MILD upgrade on the hydraulic cam and .035 shaved off the heads- stock rockers and pushrods. This is what the machinist want's to use instead of reworking the guides and I have concerns

The 2.11" Intake Valves will be fine on the 383, and will not touch the Cylinder Wall.

Heads are milled .035", but what is the Combustion Chamber CC volume.

Double check to make sure that they have 'not' been milled before.

#2843906 Cylinder Heads typically left the factory with the Chambers at 88.5 CC's.

So if they have been milled {.035"}, the CC level should be
around 80 CC's.

Now the 'Million Dollar Quuestion' .......... What is the lift of the Camshaft ?
