W-31 Heads

z11375ss · 02-24-2007, 07:33 PM

Looking for a set of W-31 heads preferably from a 68. Good to perfect condition desired. Missed a set on e-bay last month by not acting fast enough. Jim

Since the W-31 used the same casting number, arn't they the same heads as the common small valve ones? Can you take a set of regular heads and cut them out for larger valves? I know the small valve big block castings can be cut out for large valves. I had a set of small valve E heads cut out for 2.07 intake and I believe it was 1.72 exhaust. They also put in hardened seats at the same time. John

I'll have to check my machine shop. Much easier to do it that way anyhow. Thanks for the suggestion. Jim
