All

I am running a comp cams hydraulic roller in my 260. 

If I remember correct I used 1.67 intake valves when I rebuilt the heads. 

Screw in studs, roller rockers, etc...

The cam specs are intake.448
Exhaust .443

Duration at .006 tappet lift
Intake 260
Exhaust 265

Valve timing intake open: 0 btdc close 31 aboc
Exhaust open 38 bbdc 2 atdc

I have stock Pistons.  Heads were milled slightly when redone. 

I had to retard the cam a bit to get the clearance I wanted.  

Runs great.  F4b. 1848, etc.
