You could put the MAC addresses in /etc/udev/rules.d/60-net.rules, e.g.:
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="11:22:33:aa:bb:cc", ATTR{type}=="1", KERNEL=="eth*", NAME="eth0"
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="44:55:66:dd:ee:ff", ATTR{type}=="1", KERNEL=="eth*", NAME="eth1"
But that never worked reliably for me, no matter what I tried.
In the end I had to use different names instead of eth0 and eth1, like:
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="11:22:33:aa:bb:cc", ATTR{type}=="1", KERNEL=="eth*", NAME="nic0"
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="44:55:66:dd:ee:ff", ATTR{type}=="1", KERNEL=="eth*", NAME="nic1"
And also rename /etc/sysconfig/network-scripts/ifcfg-ethX to ifcfg-nicX and
modify them accordingly.
HTH,
