Back to the valves.
I just took a valve out of a head and the magnet only stuck on the TIP. Do you need a super strong magnet? I just used a telescopic one used to things you drop in hard to get places.
Yes I did check out the website. The prices seems to good to be true. I am in the market for two.

The valve stem is more than likely 4140 steel. Friction welded or stun welded to the inconel head. Stainless wouldnt work well in a valve guide because its a softer material. The 300 series stainless isnt magnetic. It has very little carbon. The 400 series stainless has some carbon so a magnet will stick and its a little stronger. But its still a softer weaker material than carbon steels. Just a little machine shop info from a friendly machinest. Bobby

If you are running a gen 5 or 6 there are two bypass valves installed in the engine block one for the filter bypass and the other one is for the gm factory remote oil cooler witch is up inside the block where the threads for the remote adapter would bolt up to the block remove the one in the middle. where the adapter is and the one offset needs to be changed to a 30 psi or plugged so all the oil will go throught the filter and cooler.
Dont run the engine untill you have the right bypass valve or you will be removing the engine due to you buring it up like a lot of other guys have done. I spent a lot of research on my set up with the right bypass valve install I'm only running a filter on the block and I'm motioring the oil temp then going from there run a good filter like napa 1061 wix do not run fram they are junk.
Do a search here on bypass valves if you would like to talk to me about the whole set up give me a call @ 734 383-0730 ask for Dale

Ok, here's the deal I ended up with and info I found out, GM marine engines carry NO warranty from GM, any warranty is from whoever you purchase from, and that could become a joke as I found out when I had a issue on a pair of new GM 454 marine engines. if I had it to do over again I would have bought GM crate engines from GM performance parts, made the changes to marine use, and as long as you have a vin # you can use you get a 3 year warranty from GM.
