Unlike the Cobra Jet in other incarnations(428 & 351) the Cobra Jet 429 head is not really any different than a Thunder Jet head. Now the Super Cobra Jet is a completely different one with bigger valves and ports.

With the variations between the 2, hydraulic cam vs. solid,intake differences,etc. I guess my memory is fading on the heads. I thought it was only the SCJ that had so big ports that they had a leak at the valve cover bolt if it was run without the covers. I guess they both had that. :eek:
