There might be a slight difference in heat retention, but nothing to worry about. Aluminum valve covers can shed heat better than steel if heat is a concern.
There are durable chrome-like
carb and intake finishes available, but usually they're not actually chrome anymore. Look almost like it, though. Edelbrock has Endurashine intakes and carbs as well as polished intakes. They also have a line of dress up parts
The biggest problem w/chrome dress up parts (valve covers, oil pans, timing covers, breathers, air cleaners, etc.) is the fit.
Oil pans and timing covers are notorious for having a poor fit when they're cheaper quality aftermarket parts. Both have a seemingly simple shape for the most part- especially the timing cover, but there are areas on both that are thicker/reinforced on the factory parts that may be missing on aftermarket parts.
Bottom line is to use the good
quality parts. Besides the Edelbrock parts, GM has licensed Proform
to do their dress up parts, so that's another place to check out.
