Do conservative Presbyterians accept 4-point Calvinists?

I realize that many conservative Presbyterian churches (PCA, OPC, etc.) have fairly basic standards for membership, not requiring much more than baptism and a basic affirmation of faith, although stricter doctrinal requirements are placed on people who become office-holders. What I'm wondering is, how involved would someone who is an Amyraldian 4-point Calvinist be allowed to be? (Or someone who denies double predestinarianism, for that matter.) Could someone who holds those beliefs comfortably attend a conservative Presbyterian church if they hold other Presbyterian beliefs (infant baptism, spiritual presence view of Communion, etc.), or would they be better off in a different denomination?
