You can get a TB IV in many curves. I also believe in using the TB I am currently running V8-HP.

Im still reading, but since im a novice regarding these engines ill just listen and google😁

looked up the promaxx heads, and it sounds stupid to not use those! They are going on the items list..

everything starts with "its just 5000$", and end up at 15000$. As going fast should be! 😎

My machinist has a sign in his shop that reads, "Speed Costs Money......how FAST do you want to go!"

close. what I tell them is "speed costs,,,, how fast can you afford to go?" everyone wants to go faster, not all of us can afford to go faster.

Check out Flotek heads also. Very good reviews. A guy on a BBC forum just did a street 496 and made well over 600hp with their 290 oval ports out of the box. They have quite a few head offerings and prices are very reasonable.

Im running the AK racing alum heads and am really happy with them and the price. they come completely set up for your cam. .. Granted I run a belt driven intake manifold, but subtract 100 hp for that and your right in your desired hp range with a 454 and 731 cam.

My dad always told me that “Racing is like a poop sandwich - the more dough you have the less you have to taste the poop.”

As said an air gap manifold, 731 cam, and good heads seem to be a pretty proven recipe around here.

you won't be disappointed with the promaxx heads, when we brought these out to our marine industry a few years back, we had a tough time making believers of some... and now here we are!!! They're also available in CNC profiles that will rock your socks off !!! Feel free to reach out if you need any help or advice. I can hook you up

Thanks Rob, my heads are based off that Promaxx head the OP is referring to
