RE: Medium Riser 390?
By McQ - 08/29/2005 5:01:03 PM; IP 4.242.45.116
Do you mean you're running medium riser heads on a 390? That's certainly possible but how are the 427 medium riser valves fitting in the 390 bore?

Maybe you have the "early" heads ('66 and back)? If so, yes, you'll have to get headers specifically to do this.

I think FPA has just the set of headers you need. A friend installed a set of their tubes on his '67 GT fastback 390 running a set of C6AE-R heads. They fit well.
This thread, so far...
