That's what I was hoping! Did some research and I'd have to change the intake, reroute water pump, different rockers, etc. Decided to fix the crack instead.

Lope sounds cool, but I choose cams that give a smooth idle and low end torque, so I'm curious if you're happy with what you got.
Regarding the vortec heads, just be sure that they are not cracked as well. They are prone to cracking and hide the cracks well. Don't want you to end up with the problem you're fixing.

This engine got the Melling MTC-1 cam. I'll give you a solid update on performance within the next few weeks... It does sound righteous at idle before you bring the timing up! But needs a lot of advance to run properly.
Unfortunately with the cracked head, leaking valve stem seals and an over fueling Quadrajet, performance was lacking throughout the past year. There was definitely a noticeable power increase from the previous engine though, but all the other factors really hindered performance.
Took a chance and brazed the crack in the head. Braze wet into the cast nicely so I think it'll be okay. In the process of re-assembling the heads now, should be back up and running end of next week.
