So I read the post form Tim on the HAMB about C1TE heads being good as G heads if they are worked.  I have a set of these and G heads are hard to find up here in Canada it seems.  Shipping form the states is expensive too.  I have a set of ECZ-C heads on my running 272 in my truck now that are already rebuilt.  So to work the C1TE heads need to put in larger valves on intake and hardened seats in the exhaust.  These heads came with from what I here sodium filled exhaust valves?  Is this a big plus or would most just replace with normal valves if can be done?  And these are posted so can take more off and less chance of gasket problems.   I want to stick with a 2 barrel for appearance but may change to a Holley 2300 from the stock 94/2100 I have now.  So may not need the big valves to build a good street torque motor w/ high 8:1 comp, either Isky or Schnieder torque cam and custom headers from a set of chev block huggers with y flanges put on and dual 2" pipes and mufflers.  Maybe ECZ-C heads are good for now.

Maybe I am a loon but always have thoughts LOL

Did he say they're as good?  I thought he was trying to say not to disregard them because they can be made to provide good street performance.  Smaller valves, less flow and less compression can't be as good.

I think reworked C1TE's can perform better than ECZ-C's and those were use during the 2nd most powerful year.

If yours used sodium filled valves, just use regular valves.  I think it will require different valve guides to get it down to the regular size.  That shouldn't be a big deal at the machine shop.  Go ahead and install the bigger intake valve.  It's not going to hurt.  While they are posted, you're probably not going to need them, but it does kinda future proof it.

Charlie is right, I did not say as good but certainly a good alternative.  From what you have written they will be more than enough for what you have in mind.  As for the guides you can replace the 7/16"  with 11/32" with no problem, I just did that very thing on a set of 113s.
