273 Mopar heads, stock or Eddy?
 

Hi folks, I'm collecting parts for a 273/235hp J/K/L Stock class Valiant and would like to know if I should stock up on factory heads or are the Edelbrock's the way to go? I have access to the factory heads but I hate to spend the money if they won't be used. Thanks!

The 4323302 was said to be a good choice at one time.

We need all the help we can get :D

If you can find the edelbrock heads they would be fine. I have been looking and not seen a set in over 2 years. The bill to make them work might knock you off your chair. I have a set it and nothing even comes close to working.

The iron heads made great power. No need to spend prohibitive money trying to make the aluminum heads work.

Suggest you contact Bill Bushmaker, Angela’s Valiant was always FAST with that combination

I have several dozen different number 273 Heads.
They are not expensive or hard to find!

Re: 273 Mopar heads, stock or Eddy?
 

I run the 675 318 heads on my 273, they work good, the 302 heads are prone to cracking.

Re: 273 Mopar heads, stock or Eddy?
 

Are the 302 heads hard to find without cracks? Or do they crack after prepped and raced?

Re: 273 Mopar heads, stock or Eddy?
 

A lot of the 302 I find are cracked between Intake and
Exhaust Seats OR Exhaust seat to Spart Plug hole.

Usually, they do not cause a leak but I am reluctant to
spend a lot of money on them if visually cracked.

I believe they overheated in street use before i found them.

I have never cracked any small block Mopar heads that were in
place on my races cars and were not cracked before that.

What is the catalog number for the Eddy heads. The one listed on nhraracer are big valve heads. Do you have to put smaller seats in the head?

Re: 273 Mopar heads, stock or Eddy?
 

Yes you have to change seats and the make the runner the same size as OE head you're replacing. Next question becomes how to do that legally!

Re: 273 Mopar heads, stock or Eddy?
 

Yes. Get out the wallet. I have a set and the work it takes is not rational. Look at the CC numbers and get to thinking about that for a minute.
