Ported Heads

[86 TR]

How much improvement can one expect from a set of ported cylinder heads??

Thinking about buying a set with the intake to match.

Just looking for some input.

I asked that question to one of the vendots who sells them and I was told 50 hp with no other changes.

.3-.5 @ 4 mph i would say thats the average. with no other changes.
