Also: I'm going to just keep my AFR 1399 heads with the 1.9/1.6 valves that they come with. No fit issues with the BOSS302 block. If I declare the car for SS/CS I can run the Combo legally. Aluminum heads any valve size 10.5 lbs/cid. The index sucks O2 (10.30) but I have thrown t he book at my car over the Winter. |
Sorry Dale, you cannot run aluminum cylinder heads in SS/CS class, only cast iron, inline/wedge heads only.
