1.4 head is shit as fuck, for the hassle of a block swap go rst
if there are parts laying about and a good working 1.4 then could spunk as weekend into it i guess
if i had a 1.4 summet laying there i'd prob frst it if it was efi with a little t2 but only just to see how long 20psi lasted thru it, flow on a 14 head is terribe tho
