My wife has a 78 Cutlass Brougham, with the stock 260 engine. The 260 has at least one toasted valve.
I have a spare set of #4 heads, from my '67 330, that have less than 200 miles on them since being rebuilt. I am wondering about the feasibilty of replacing the original 260 heads with the 330 heads. Will it work?
I'd much rather replace the 260 with a 350, but am hoping the head swap will work long enough to locate a relatively healthy 350.
Suggestions / opinions welcome (don't be brutal)

 

the chambers will overlap the cylinders, sorry bud but your stuck with the stockers

 

You could probably get both new heads for 100 bucks at precisionengine.com and they might buy your old ones.
