I'd think a zero deck 440 w/ 915's would be a tad high thant 11:1 even with fel-pro's.
That said Fel-Pros.




How can you say that with the info he posted ?

I just ran the numbers assuming .040 overbore , 5cc valve reliefs, 80 cc heads and a 4.410/.039 gasket and get 10.55 , if the heads are 76 it's only 10.97.




I was thinking they'd be closer to 76cc. not 80.




They are over 80 stock , the set I have are 81




Mine must have been milled a bunch because they were 74. I though stock 906's were 84?
