Hello,

What are the best BBC ( Big Block Chevy ) cylinder heads for street/strip use for a chevy big block engine with 4.600" bore, 4.500" stroke and 598ci displacement.

what is the best intake runner, intake valve, exhaust vlave sizes best suited for high velocity/high cfm flow cylinder heads?

is 320cc intake runner size, 2.350" intake valve, 1.88" exhaust valve sizes best suited for high velocity/high cfm flow BBC cylinder heads for street/strip use?

what are the best companies that make best BBC cylinder heads?

I feel like that Brodix is almost the best company for BBC cylinder heads.

I didn't like the Dart's BBC cylinder heads.

what would you say about the Dart's BBC cylinder heads?

what are my options in BBC cylinder heads for what I want?

shall I go with 24 degree BBC cylinder heads or 14 degree BBC cylinder heads?

I want the BBC cylinder heads for a big block conversion in my 1996 Impala Caprice SS with modified 4L80E automatic transmission.

Thanks for help.

You would want at least a 345cc head. Why do you not like Dart? They are literally one of the best options out there, Richard Maskins is one of the greatest innovators of the industry and continues to develp some of the best stuff in the industry. We run the 345cc/121cc on most of our 598/632 builds (#19300132). The other option for me would be AFR or Brodix, you really cant go wrong with these 3.

Thanks for the replies , looks like AFR BBC heads would be the best option for a 598ci BBC.
