Questions on e-Tec Heads - Any problems?

Looking to upgrade my '86 L98 with e-Tec heads - notice the plugs are different - any problems with headers or exhaust - if there are problems any good solutions?

Also any reason why these wouldn't be good heads for a street only motor focused on torque (the 170cc version)?

If this is the "Vortec" type head, it will require a new intake manifold base.

I you have the aluminum heads, i'd put the dollars into the intake first.

I think the e-techs where set up for somthing like .550 but im not sure.
