As I was driving on the high way i noticed a ticking noise coming from the engine compartment. As i drove further it became a clacking sound that increased as engine speed increase. Being far from home and on the highway i pulled off at a rest stop and lifted the hood to listen. Sounds as if it is coming from the top end on the passenger side toward the rear of the engine. I could here it real well ther with the stethascope.Suspeting a failing lifter.Planning on taking the intake off and checking on Sat. Any other suggestions anyone may have would be appreciated. Bob

Here`s the poop.
No loose rocker nuts, no bent or broken rods.
lifters showed a little wear .
Maybe a collapsed lifter,don`t know.
Dug a little further because i didn` tlike the way the vavle stems looked when i peeked through the head ports. Pull the driver side head off , flipped it over and S@@# .Valves went from soot black to bright pink. Not the way they`re supposed to look. Also saw some scoring in the #7 cylinder.
Made up my mind. time to build a motor.I`ll try to post pictures as I go.Want you guys to see this head though.I`m goint to start
pricing the parts.I`ll tell you what I`m looking to do.
I want to build out a motor with alot of torque,375 -400 hp.I would like to keep the Q-jet as I just re-built and can save $$ there. REplace intake manifold,Cam,lifter,etc. Replace pistons.Headers with side pipes. I want to budget this around $4500-$5000 Including Machining.I`ll be taking the motor apart and putting it back together with a little help from my friends. so that will Save some $. For those of you that gave me advise on the Torque Thruster wheels thank you.But they will be on hold awhile.And I was looking forward to that Turkey Rod thing in Daytona.
Any opinions?
Jump in anytime now!
Thanks, Bob

The pink can be from octane boosters. Some boosters use a chemical called MMT for short. It leaves pink deposits.
The other problems are another issue. You may want to consider building a 383 stroker if you decide to go full tilt.

OH NO!! So, using an octane booster with MMT is not a good thing, huh??
