I have a 292 with ECG-D heads and have swapped out the original two barrell intake manifold with a ECZ 9425-B four barrell/500 CFM Thunder Series Edelbrock. I have a chance to pick up a set of 312 ECZ-G heads. The present heads, I believe, are off a 272.  I am wondering about picking up the ECZ-G Heads and having them rebuilt so I can swap them out at a later date. I can get these heads for around $275. They have been magnafluxed and show no cracks. I need an opinion or two on whether or not this head swap is compatibale and if $275 is too much to pay for these heads.  Thanks!
