(wanted) Edelbrock 60177 or nicely worked RHS heads

You mentioned it in here, simple fix. There are some benefits to going closed chamber as well.

Good luck with your search.
Many people say the closed chambered heads have a better quench area. What benefits does the quench area provide? Ive always ran open chambered heads so that is a new one for this old school 340 guy. Mabe im thinking wrong, if I could benefit from the quench mabe i need to change the heads im hunting for. Thanks, Kevin
