What About Edelbrock 340 Heads?

It’s great to run as much quench as you can but there is a area where you have to realize that the rod stretches and how much and when is based on not just the material but the quality of it, how everything was machined and altered.

It just gets to risky after awhile. It doesn’t make sense to push it especially in the street. I’ve run .030 quench and that was just fine enough. Normally it’s .039/.040 but not more than .050 where it is said that’s the most away you can run it before the bennifts are lost.
