There seems to be a belive that you can't put
big valves/aftermarket heads on a 260...
BECAUSE of the bore size.
Not the case.
The typical problem is piston to valve clearance.
Standard 260s have flat top pistons, no valve reliefs.
I have a 260 with a 3.800 bore, with 351 heads and 1.900 intake valves.
However, It Does have aftermarket pistons with valve reliefs.
...Of course, all the BIGGER Stuff in the combustion chamber of a 260
KILLS compression, so pop up pistons are needed, just to get back to
square one...
