there really is no difference in 2v and 4v heads for windsors except for compression ratio. with clevelands its a big difference though

I have a 1986 Pontiac Bonneville with a 6 cyl. I was wanting a healthy sounding exhaust note with it. How can I go about doing that? I'm wanting to keep it mellow until I stomp on the gas, then have it loud. Would glasspacks be the best option? Also I want it to wrap when revved up. Thanks for the help.

I would go with the 68' 302 4v they have 55cc chambers which means more compression the 351w will flow more but lower your compression, take the 302's and put bigger valves in them, the 351w will need bigger 1/2 head bolts too. just something to consider ;)
