I've got a set of Kelford 272 cams in my ej205 heads right now. I'm wondering if I can use ej257 heads and put in the Kelford cams with the ej205 cam gears. That way I could avoid having to send out my ej205 heads to be chamber matched and I'd end up with a set of heads that are less prone to cracking between the spark plug hole and valve hole. Thoughts?
