349 CI on the cheap
Terry,
302 heads are out there and sould be in most junk yards, and will work the best on a 318 but if a 349 engine is what your after then the 360 1.88/1.60 valve heads will work better and they are out there since 1967, so it's kind of take your pick as most all the castings have the same ports. IMHO I would go for a set of 915 J heads with 1.88/1.60 valve to start with. Hope this helps.
