What's your thoughts? Which will make more HP? About to pull the trigger here.


Respectfully, for sure you are dedicated to this hobby and you get things done! You are asking for thoughts. Are these thoughts to help you best achieve your new goals? I'm eager to offer some suggestions based on your responses. For posterity, we should consider the last motor you built (which i would need a refresher on details) and how it ran. Other than the heads, what are you changing? Where you happy with what it ran before or is your plan to step things up everywhere?
MY thoughts are to ask some relevant questions:

1) What's wrong with the heads you had before?
2) What are your goals? (HP/ET?)
3) Are you imposing any limits to what parts to use? Are you imposing limits to how much you want to spend?
