I'm considering purchasing some AFR cylinder heads for a 383 that will be a street/strip engine. About how much bottom end will I lose using the 195's over the 180's? I have not decided on a cam yet. Compression around 10:1. I was looking at Lunati's voodoo series cams, duration @.50 233-241, lift .504-.525, Lsa, 110-106. 2200-6400. All opinions appreciated.
