Ok, I have taken this to be true for over a year - because I heard someone else say it. But I never really knew exactly what the deal is.

It is the same block, so shouldn't the exhaust manifold pattern be the same? Is the only issue the distributor?

I would like to hear from someone who knows as opposed to canaries like myself

the na head is different from the tt head. ive heard that the na head flows better, however.

The n/a port spacing and manifold bolt pattern are different.

not completely sure if it could work but use a adapter plate

like so(hehe its hitty but hey)

the so the exhaust ports go to a mini manifold that relocates the exits to the turbo manifold or thats teh idea, i dunno if sapce wise it could work but it might i dunno

ok jsut saw DaveH said bolt patter was different might could re drill tap the adapter???
