I have a set of heads sitting in my shed that have been there awhile. Got the number off of them and was wondering if they would be OK heads to have a little bowl work etc done on. I have a 402 in my car running now and could slowly have work done on these as money would allow. So whatca think about these heads?

3909802, could be 3909862 but I dont think so.

Thanks

All oval port heads flow excellent with a mild rework. With closed chamber heads, you can get good compression with a small dome. If your 402 currently has open chamber heads, your compression will get a nice boost by changing over.
