Yes ... The one I had did ..

I had a jet-V suck the valve head off ..Then the valve stem do to the spring shot up and broke off the rocker arm .. <img src="/forums/images/graemlins/zombie.gif" alt="" />... The motor really sounded DOA.. Lots of knocking out of the motor ...It was not a 'knock' it was the air rushing out the jet-V guide do to the stem and spring and lock was now up in the rocker valley ...

Installed a new jet-V and rocker and off to the races.. The jet-V head did drop into the motor ..But the 2.6 'steamshovel motor' sucked up the valve head and spit it out and the motor lasted another 100K ... Then did a 'lawn dart' move and killed the truck ..LOL...

Got to love the old "SS M 2.6" <img src="/forums/images/graemlins/patriot.gif" alt="" />

Hope that helps..
