Re: 409 Parts Wanted
Knappy,
Check your cowl tag. IF your car was built after the 2nd week of Nov. '63 (11B) you should actually have 583 heads, not 690s. That's when production switched from the 930 (.520" lift) cam to the 7735 (Z-11) cam. The 583s are identical to the 690s except they have more meat under the valve spring pockets, which allowed them to be machined deeper to accomodate the higher valve lift without coil bind. Do NOT put a Z-ll cam and 690 heads together. And don't try to machine the valve spring perches on the 690s - you'll hit water.
By the way (just my opinion), you're getting into 409s at a time when things are more expensive then they've ever been. Expect to spend $2K for a "decent" set of heads.
Larry sent me a pic of the '64 you bought. Bahama Green........neat!
