replacement heads for my 318

[mightymopar]

Will any of you guys give me some help on heads for my '67 318. It has any Edelbrock alum. intake and 500 cfm Eddy. carb. I have 2 650 cfms if one of them would be better. There is a Comp Cam #20-221-3 in it, valve lift .447 .455. The more research I do the more confused I get. Would stock 308 heads be the way to go or W2s, or are they the same. Would magnum heads fit. Can I keep the same springs and valves. The engine shop that installed the cam and bearings also installed CC lifters #822-16 and CC #901-16 valve springs. Thanks for any help. Dave

302/714 casting heads are good on a 318. If you want to go the Magnum route you'll need new lifters and push rods.
