Hey guys, what's the max spring pressure you would run with T&D street rocker set up in aluminum Edelbrock heads. I am set up for 650lbs over the nose. Should I consider putting in time-serts while the heads are off? T&D said it would be no problem, but I worry about pulling a stud out of the head. That's the problem with machining taking too long, it gives a guy time to worry about stuff instead of slapping it together and just running it!!!! Jim
