I have a set of E heads form one of the first runs. Hammered on them on my 455 and a solid roller, now on the 500" IA motor with an even bigger cam and have accidentally buzzed it to 7000. KRE hand ported them before they did CNC so big they have pushrod and head bolt tubes and never and issue. Dan Barton touched them up and little and added some spring locators vs just a shim like KRE had. Only issues I've had is oil drainback but most aftermarket heads of many brands do not having the large drain holes of factory iron heads.
