Could there be any problem running 2 heads of differing casting numbers? Though valve and combustion chamber sizes remained equal, would the different flow of the runners really mess things up? Thanks.

We ran a 461x and a 492.Both were the same valve size couldn't tell ya about the flow but ran it like that for over a season and it ran fine.
