Does this mean I need new heads or can I attempt to clean these out? I suppose even if I could get all of rust out the valves will be frozen in their seats.
What no takers on this questions? I think I know the results but was hoping someone would come on here saying "no you can wire wheel the rust out of those ports".
Thanks for the response. I was going to take em' off this weekend but weather did not allow. It appears to only be the Port side but if they are going to grind valves & all they should both be done at the same time correct? Sad thing is this is a new Jasper Motor that has sat for 10yrs. Not sure if the heads came with the block or if the old ones were used. BOAT Bring Out Another Thousand! :facepalm:
If there is that much rust in the head(s), what does the block look like. Pull the heads since they must be pulled anyway. Depending on how much water was in the block and its condition, you may have a 10 year old but new anchor. If there was water in the engine and it was allowed to freeze -- well -- you know the result of that scenario.

Yes! REALLY Frustrating! We moved as the motor was being installed. When everything was done I went listened to the new motor run & paid the man. Even before I left I opened up the petcock valves on both side of the block. I did make the mistake of not unscrewing the plug out of each of the manifolds. These were not in the best of shape & had been welded several times before so I am not upset these need to be replaced. I am new to boating so I guess my thinking was if I open up the lowest point on the engine the water will drain out & if gravity didn't do it's thing I would expect the 400 mile drive back to our new house would have bounced out any remaining water.

Well it doesn't look good. The heads are definitely toast. Cylinder 8 obviously had water in it. Since this is at the ridge line is it possible to clean it up, hone it or something? Just makes me sick this was a brand new Jasper Engine. How hard is it to pull & re install an engine in a boat. It almost looks easier than doing a car swap.
Have a 18' 1978 Mark Twain 351W OMC. WOW! I was hoping the drive didn't have to come out. I have done several automotive motors but have never touched a drive before. What's involved in aligning the motor? I assume it not as easy as just putting it back into the motor mount holes it came out of.
Hope I am not getting over my head here but money will be getting really tight after I buy this motor for the second time. Plus I don't know if anybody around here will even work on a OMC.
Really getting discouraged & want to just give up but then all of the hard work & money put into it would be for nothing.
