you will likely not get that detail. Testing spring tension, stem length etc. etc. is crucial for high performance heads but most shops don't specialize in that kind of wor
That sounds great for a race engine.

Nothing wrong with doing it all yourself, we all have our limits. I'm the guy that rips out the plumbing in the house but doesnt think twice about dropping a head off at the machine shop.

here are a few pictures. note the scoring on the camshaft. is it safe to lightly polish or should I even worry about it?

If you can catch your finger nail on it, get it worked over or replace. "Save" it will prolly be but will eats lots of other parts before self-destructing down the road.

Chris and engine will benefit from careful assembly! There 'free HP" in doing things right. Lots of engine builders guard there engine building processes closer than their daughters!!!

dissenting opinion: leave it as it doesn't hurt anything. Not really any different than a groove deliberately cut for oil (see some grooved journal bearings for examples.) Its not going across the face so not a problem IMO.

Just make sure the large particle of crap that originally made it isn't still embedded in either the cam or head. Feel for it and use magnification if needed. IF its still in there, I suspect its stuck in the softer aluminum head or bearing cap.

Not really desenting as much as pointing out that the grove part isn't a problem, just the ridge if any. I did forget to mention finding the culprit

Thanks. Am getting a good idea of what this requires. Looking forward to getting back home and get this started.

Have read through many how to examples of cleaning the block. Is there a preferred cleaning method?

Ok..so set a goal of pulling the head and removing all that was needed to do the timing belt by Sunday...succeeded. Spend a lot of time cleaning as well as the car has been leaking oil for a while.

Head came off pretty easily. Couple of obvious needs include a few valves bent and one rocker. But I have two full heads to make one good.

Head gasket came off pretty clean from the block. A couple of the piston heads have a slight indent where they hit the valve. Is this something to worry about. I don't intend to go any deeper into this engine so if it is this car is heading to the donation yard.

Otherwise, tomorrow plan to disassemble the head, and ensure I have one good and get needed parts to a machinist to look at.

Picture below of the block. Cleaned it up some but other than checking for it being flat, don't plan to resurface with any abrasive material unless it doesn't appear flat. Any recommendations appreciated.

Little update. Stripped the head from the car and now have 11 good valves and a camshaft without the scoring. Will try to get the head, camshaft, springs to a machine shop tomorrow. I tried to check if it is flat, seems to be, but will let them verify.

Spent some time on the block this evening. It also appears flat and so hopefully will begin installing late this week, though I will keep cleaning the block till I am comfortable I have it clean enough.

Been quite a new experience for me. Let's see if I can get it all back together.

Great job! I like to see someone dive in and explore...it sounds like you are on the right track and will have a successful outcome.

Thanks...an exploration it has been...

If there is anyone local who has experience with block preparation and would be willing to come by and take a quick look at the block sometime this week...I have plenty of beer in the fridge..
