Big Block and Small Block Heads
OK what are the pros and cons to running SBO heads on a BBO? I know the heads with smaller chambers will raise compression but will flow be hindered? Is there a big difference in the valve size to worry about? Can you port and polish the SBO to flow like BBO heads but gain the compression? Problems with intake to head port matching? I know you can mill the BBO heads to raise compression but why if you can acheive the results without?

Sooooo...if I were to port my own SBO heads that I already have...and have 2.07 and 1.68 valves in it...and want to put them on a dished 455, there really wouldn't be too many cons, would there? haha I do understand it wouldn't be financially wise to pay someone to do it, but if I already have the resources available...it wouldn't be a terrible decision, would it? I'm only saying this because I already have everything and don't wanna spend money on another set of cores. Yup...it's an older thread, but just wanted some clarity.
