blacktop head on silvertop block

[turbomad]

Is it a straight swap or do I need to modify anything to fit the head like wiring for sensors or all the same

if its 3 plug ecu then some plugs on inlet may be diff

[turbomad]

Yeah its 3 plug was tempted by a s1 rallye inlet could I use that instead

[turbomad]

Reason I'm doing this is looks like my h/g is gone so thought I'd change so I can get more revs but could I just fit blacktop valve springs and rockers to the triple plug head and does a cam from a blacktop fit a triple plug head?
