Aluminum heads $ per HP?

A lot will come down to how big the motor they’re going on is, and probably even more importantly...... how much power you’re trying to make.

If we are talking about something “ready to bolt on”, where the only involvement from the end user is paying for them........

If you’re trying to make under 400hp from a stroker, then pretty much whatever 340/360 sized heads with 2.02 valves you can buy cheapest will likely be the best bang for the buck.

However, if you’re looking to make 550+, then the higher flowing heads are going to end up being more cost effective.

Obviously, those who have the tools and skills to do some blending/porting themselves can buy cheaper heads and do their own work and save money that way.

As with almost all of it.......”it depends”.
