[classical glass]

Hi everyone, I have a 427 stroker and I'm ready to install a set of aluminum heads. I want to purchase a complete assembled set that's all ready to go. My questions are are there different compression ratio to pick from and which one is the best for the street. Are there any incidentals that should be considered when ordering them ie [ss valves, teflon valve seals, sodium filled exhaust valves etc] I only want to order once and want to get it right the first time. Last who manufactures the best items? The car is a semi show car and driven only on the street. Thanks for your time.
