I did , what was supposed to be a gasket match clean up on my brother-in-laws 429 CJ marine engine heads. I reached as far as I could into the runners with a carbide tip on my die grinder, then smoothed using a drum roll. I just removed the intake after a very short run time since complete rebuild. I had a couple lifters clattering, suspecting a flat cam. edelbrock cam kit installed on rebuild. I found 3 tiny cracks. Diagonally down the runners. Is there any such thing as a magnaflux system I could use with the heads still bolted down? There's no sign 'yet' of coolant leak, maybe not a crack. Any info shared is appreciated.

We used some stuff at work for checking steer axles for cracks. Cleaned it up good, sprayed it with one can, then sprayed it with the other. A crack would show up if it was there. Can't think of the name on the can though. A google search should yield something. Later, Travis

Maybe I’m not understanding the problem here, but with my magnafluxer, I would make sure the valve was closed, tape off other ports, Valley, , maybe stuff tissue paper down around the valve,put my machine on it , check it. Then vacuum it, blow it with compressed air. And call it good. Bones

Old timers used to soak area with gas where the was a crack. Then, they would gently wipe area off with a dry rag, The gas would come out of the crack. LoL Try it, it works. Be careful with the gas.
I'm an old timer. Must have missed that one. Sounds simpleist. Thanks
