Rectangle Port Heads
 

Wanting To Change A Big Block Gen 6 Oval Port Motor Over To A Rectangle Port Motor. I Have The Intake Already. I Need A Set Of Heads,
Anyone Have A Set Laying Around? Cheap! :d

I just might have a set here in a few weeks. I am probably going to change over to aluminum heads. My heads are off a 2000 Gen 6 502. Will they work for you and how much $$$$$ are you willing to part with??? They are supposed to have around 75 hours on them.

I have a set, but if your installing them on a 454 you wont be happy with them.

Yes I Think They Will Fit, There For A Friend, I'll Ask Him What He Is Willing To Pay. What Do You Think Is A Fair Price?

Why Not? We Are Changing Pistons, Cam, Intake And Carb.

Racer-

Give me a call at 847-902-9702 when you decide. I will check to see what the heads are worth on my end. Just a note-- I do not have them right now. I am about three weeks away from them being in my hands.

Square ports are to big for a 454. You will be better off with a set of large oval ports. Like a set of 049's or 781's.

Yes, What Chris said. The rectangle ports are too big. They don't flow enough air for the volume.

Look at the edelbrock marine heads, they are quite reasonably priced and come with the good valves and guides. I think you will be happy with the rect port heads as long as your parts compliment each other, as long as your goal is WOT max performance and as long as you spin them into the mid 5k range. If buying new though, the ovals may be a better all around choice. Don't forget to take advantage of the aluminum head and bump your compression 1pt or so.

Edelbrock ovals 110 cc , the rectangles 119 cc chambers. Ovals will give you the compression bump with out changing pistons.
I run them on my rig . Engines seem to make good power with great throttle response.
