dragonfire Posted June 28, 2006 Share Posted June 28, 2006 i have an 88 gl. i was wondering if there were heads that have exhaust ports differ from mine i have single ports on each side. are there heads with daul exhaust ports and could i swap them on my engine. or would it be worth the hassle? seems maybe dual ports would be better than one.

mikeshoup Posted June 28, 2006 Share Posted June 28, 2006 Only single port exhaust on the 80s soobs. The MPFI and Turbo heads have dual port intakes, but not dual port exhaust. Link to comment Share on other sites More sharing options...
