Is this 5.0/289 combo OK???????

Is there any problems with combustion chamber size or port size when using 289 heads ('65 vintage) on a 5.0 roller block?

I am going to use a 5.0 roller block, 289 heads a Edelbrock RPM manifold. I just want to make sure that when the motor is finished, I can bolt up the A/C, power steering and alternator brackets in the stock locations.

Thanks,
Ron

The heads have been milled.. Will this make a big difference?

I believe it was .001?? Does that sound right? I will go in the glovebox and check.

That's a damned good machine shop to be able to mill .001. That's about the limit on the vertical mill where I work if you took the time to true it up right.
