Camshaft timing findings

Reality is that most stuff that comes out of the pump is very avarage, no matter what part of the country a person's in. It is getting better with Ethanol blends though. Could have a valve seal issue, maybe even a guide, how do the valve stems & back sides of valve heads look when looking down/in to the ports? Gummed up at all?

Ryan,

Thanks again for your input. Not sure about the fuel here and the only additive over the years has been Sta-bil for storage off and on. I imagine it sucks here, but we do have one station (Union 76) in the Honolulu area that sells several types of racing fuel, but have not checked it out. Looking down into the ports the intake side is really clean except for the secondaries that are a little gummed, but looks normal. The exhaust side is another story and maybe I'll be able to take some pics later as they look very gummed up. The heads are in the process of being shipped to Greg Van Deventer so we'll see what he finds when rebuilding these. Gotta head to work so thanks again.
