Thanks everyone, of course this is what I wanted. Like I said, a stupid ACL question...I'm blaming heavy medication, sorry for the noise!

This is applied to an inbound interface(s). We want anybody outside to be able to reach ports 80 and 443 of any host on our network, no matter what, then block ALL other access to select hosts, such as 2.2.3.4, even ICMP. However, as soon as I apply this rule to the interface, ports 80 and 443 of that host become unreachable. A telnet to 2.2.3.4 443 gets "Connection refused" until I tear out the deny ACL above. I even tried adding udp for both ports, to no avail.
Your ACL is apply the 80 & 443 as source ports, not destination ports.
You probably want: permit tcp any any eq 443 permit tcp any any eq 80 deny ip any host 2.2.3.4 permit ip any any
