Better heads

Well, yea, there probably is more head there than the engine needs right now. But it will work OK.
Theres a catch in cylinder heads though. It's the money in your pocket vs. the choice of heads. In many cases, people want to know what would be the best head. OK, cool. Then theres, I only have $500 to put forth on the cause.
Do we port the head we have or do we go for a set of larger heads?
Alot is build dependent and what we are willing to live with....or without.
