Engine has a performance cam in it already, I don't know the spec's (was in there when I bought the car), it idles fine but has that nice cam sound, probably a purple or similar.

 

It also has a weiand single plane intake and a holley 750, comp roller rockers and hedman shorty headers, so I'm sure the extra flow capacity of the 452's will help....

Are you going to run the same cam and or upgrade the cam at the same time

Hi all,

 

   So got a bad head gasket in the 383 in my 64 Newport Convertible, so time to pull the heads.

 

They are the original 516 castings, and, based on the variety of valve tip heights (and the fact that I had to shim the rocker shaft on one side just to get one valve to close all the way), they need some help.

 

I have a good set of 452 heads, they have the hardened seats and the larger 1.74 exhaust valves, but are open chamber heads.

 

The 383 in my car is a 1966 2-bbl engine, with 9.2:1 compression.

 

If I use the open chamber heads anyone know how much compression I will lose?

 

And with the better flow and larger exhaust valves in the 452's help make up for it in performance?

 

Any insight would be appreciated!

 

Jay
