That's small block territory.

Not for your hp goals.

Is the Brodix bb1 sts cnc 280 a good head for my goal? I know there not cheap.. But my builder swears by them.

Who is the builder monster?

Ray and victory. He didn't specify which Brodix head... But putting 2 and 2 together I figured the bb1. We spoke a few months ago and I am collecting parts now for a November-December build. I decided I am going to leave the rods and pistons and crank alone and stay 509. This motor was built last September by another builder... And I am going to have ray just check it over, because I have had some issues with it, and he will add the heads and cam for me. Then I will figure out the intake and EFI tune!

Ray builds lots of endurance stuff.

I'd have him buy the heads bare and build them.

Yea that was my plan, to buy bare and have him build... Just not sure which head to buy. Maybe I am better off just letting him make the decision.

Those BB-1 heads have a .600" raised exhaust port. May have to do some transom mods for your tailpipes. The 24* CNC 298cc Race Rites I believe have standard exhaust height.

Speaking of which, what exhaust do you have or will you use ?

That intake manifold is going to squash your dreams. Read up on it.

I will be using lightning headers... I have been reading on the intake... Seems going carb maybe my best bet. Is anybody modding these intakes to make power?

Quick search looks like ASM offers an option. I thought I read a vendor on here works them too... I will have to do some more searching

If you have a builder have him spec the build. It's a little easier for them to stand behind their build when they spec the components. Also, when the numbers don't make what you paid for it is a little easier for a course of action.
