That is a nice piece there. And for your application will be great. The only thing I would do is go to McMaster Carr and order Nylock nuts to replace those nuts so they wont loosen up. Just a little insurance.

On a few builds with mounts like that, I did try red loctite, but some did come loose. Then I switched to the nylock nuts and they never had a problem. Merc has those thin metal bend tabs but they are a pain in the a$$. And they are more money then the nylock nuts

I was putting my shopping list together at Summitracing. I discovered that inconel is brand specific to Manley. Upon further research, my 420 may already have them. That assumes the builder that rebuilt it put inconels back in it. When I pull the heads off, how can I tell if they are Inconel already? And what valves should I put in if they are not Inconel?
