i was wondering if gt 40s (cast iron ones) will bolt up to my 86 EFI
i think they should but want to make sure and if they do bolt up will they work with my speed density, and if it will run alright with the heads will the SD keep them from making a noticible difference worth the work to put them on
thanks for the help please lend me your expertise
by the way, will shorties make a difference (I know long tubes do but I already upgraded my exhaust)
P.S. if i do this i will also put in Comp cam:
