I'm considering replacing my L98 aluminum heads with these Heads . The motor is a stock ZZ3 with 2.5" rams horn ex. manifolds.

I think the Fast Burn heads were used in the ZZ430 in addition to a different cam. I'm not aware of any other changes between the ZZ3 and the ZZ430, but correct me if that's not right.

Will this be a seat of the pants difference without any other changes like a different cam? I keep reading that the L98 heads are very restrictive. I'm just not sure if it's worth changing them if I'm not prepared to do the cam at the same time.

Five things that you cannot recover in life:

* The Stone after it's thrown
* The Word after it's said
* An Occasion after it's missed
* The Time after it's gone
* A person after they die
