Budget Aluminum Heads
There is no denying that the TF240 is the leader in the “bang for the buck” category.
But…….if they’re not in your budget, then they’re not in your budget.
Any of the current crop of aftermarket BBM heads are more than capable of making enough power to reach the OP’s goals.
As are reworked stock heads……….it’s just that reworking stock heads can easily reach…….or exceed……the cost of a set of the entry level aftermarket heads.
