i may be in the wrong place but i need some help with rebuilding a 390. I have stock heads (i have no idea what the serial number is) and i have these to put on it: C6AE-R..thats all i know about them....

my question is: how much better are the these than the stock ones ?

any help will be greately appreciated.

 

Hopefully, you will get some feedback from some members, I know there are a few that have FE experience. If you don't, try our sister site, there is an FE forum there that may have some knowledgable people.
