Had my head machined flat and the block was checked to make sure it was flat. Installed arp 425s and within 3 pulls on a back road at right under 70psi blew the head gasket. Got the gasket fixed and everything was checked for flatness along with 3 retourques and my boost turned down to 55psi and I now have another blown gasket within 1000miles. No leaking coolant but lots of bubbles in my overflow and tons of white foam in the oil. I really hate having to pull the head and flush all my fluids every 800 miles so I’m thinking arp 625s and find a place to put orings in the head should solve the problem. Any other ideas to help solve this problem? With 625s and orings be enough? Anyone know a place around east bay California that does orings? Thanks
