are you asking questions in the order of 1-5? If so, don't buy new heads and not know where they come from. Find a reputable machinist and use him. We can't see where you live, but I would bet wherever you are someone on this forum knows a guy close enough to use. If your in Texas I'll refer you to my guy. He charged me about 2,000 for heads on two motors, but he does awesome work (stainless valves, hardened seats, new guides, new seals, decking, etc, etc. ). What makes you think you need heads?


PS- that is a gorgeous boat and I know everyone here appreciates you sharing! Let us know she comin!

Hold it! If that's the AMC 327 cube motor, you'd better look around for exhaust manifolds BEFORE spending dime one on it. Damn hard to find.

No, not asking questions. just order of things needed done. I am in NE Ohio. Ashtabula to be exact. The motor run great. It burns a quart of oil every 2 - 3 times out though. Carbon blowing out the exhaust. When running her she dose not smoke. Just on start ups when smoke and carbon blow out. Had 1 mech say motor needs replaced. Had another mech ( didnt look at the motor) say sounds to me new heads. He was familiar with that motor. He said that year of motor was made to run leaded gas not this stuff these days. He will look deeper in spring. This all came about last year when winterizing the boat , so neither got a chance to look deeper into problem. If i do need new motor then its a chevy 350 , or chrysler 360 . Thanks for all info....

If it is running good, leave it alone. Pull the sparkplugs and check if they are fouling. Normal for an engine to burn some oil until it warms up. Make sure you are not overfilling it by draining all the oil and then put in the right amount. Then check the dipstick. If wrong, put a new "full" mark on it. (file a scratch on it) Oil is cheap, just add more if that is all it needs. If you want leaded gas, take a 5 gallon gas can (metal, not plastic ) to the airport and get some 100 low lead Av gas. 5 or 10 gallons of Av gas to a tank will help a lot. Also good for your lawnmower.--Ed

It does sound like you may need valve stem seals. They can be replaced without pulling the heads. The only reason I would pull heads is if there was a burned valve or bad valve guides. Leaded gas only affects the valve seat and face on these early engines, not the guides. The "lead" helped soften the pounding of the valve and seat before they were hardened. I've seen engines run for years without leaded gas and never burn a valve.

If in fact you need a set of heads, I believe that all three engines share the same head (250,287,327) and there is no differences with the automotive head. Given the choice, I would go with an automotive head. Being that it had antifreeze in the engine it's whole life, it will be in better shape. The later heads (post '64?) Had AIR bumps cast into the top of the exhaust ports, but that will not make any difference.

Is carbon actually blowing out or are you referring to oil smoke? If carbon is shooting out of the exhaust....take her out and put her through her paces. Getting some heat in those cylinders will do her good. I've fixed plenty of tractors by putting a bush hog on the back and backing the mower into a pond to run the tractor loaded up, sometimes people idle/just putt with engines and they run too cool and collect carbon. If the engine runs good, I would just let it be. Put oil in as needed and spend your time engjoying (sorry for the pun) the boat.
