RE: Largest valve set for C4AE heads on a 390 bore

Just some quick thoughts here. What you're proposing to do has sure been done before. It would depend too on how much you expect to gain from the 2.19 intake valve. Is this a pretty radical, far out 390 + .030? If not, why do it? The C4AE heads are fairly common as are their equivalents, i.e., C1AE, C6AE, EDC, etc. They're not hard to find. Then work them with the CJ intake/exhaust valves and you've got a solid, safe combination. Again, just some thoughts and I'm sure someone else will give you some "advice" in the next day or so.

One last thing is how much these C4AE modified heads are being sold for? Not that I need to know but it's just that you have to consider how you want to spend your $. You could probably have a set built with new valves for around $400. That's a guesstimate based on what I've seen done around here. That's not an all out port/polish job but just new valves, guides, grinding, & bowl clean & cutting for the CJ valves.
This thread, so far...
