I'm planning on buying a short block and putting on some GT-40X Aluminum "Turbo Swirl" heads. I've heard these aren't street legal. Can anyone tell me this for sure? When compared to Edelbrock performer 5.0 heads they are almost identical except for the performer heads come with 1.90" intake and 1.60" exhaust and gt-40x's with 1.94" intake and 1.54" exhaust. Combustion chambers are almost the same also, 60cc for Edelbrock and fords' 64cc or you can get them with 58cc but i was looking at the 64cc ones. thanks for any info.
