Whats a good rookie red plate head

[kart49]

Looking for good red plate head casting number.

 

[DynoDon]

Any small runner

 

[Big Chris]

In this order:
223, 181, 136.

To add to Don's comment, it's not only the runner volume, but it's shape & geometry also play a solid role.

 

[DynoDon]

That is true.

 

[Raging Bull Engines]

That depends.

Anyone have a used or new stock 223 181 or ao1 head laying around

 

[Big Chris]

I have a 136, 181 and many 223 new as cast.

My 136 & 181 are kept for reference and are not for sale.

I like the 136 heads. Here is our red plate winning (checking out) at Daytona. It is the Red kart that starts 5th and takes the lead on lap one. We were about a second a lap faster than rest of them. We also won Jr1 pro the same day

It is gravel. It is a gear rule. Turned it right at 6500
