Exhaust Porting on DOVE-C heads

Hey all,

So I found a set of DOVE-C's that have the intake ported to SCJ Specs and are sporting a set of VooDoo rollers. all the valves are new but the guy ran out of machine shop $$$ so the exhaust sides never got touched.

Personally I would have worked on cleaning up the exhaust sides 1st then worry about intake, but hey whatever it all works out for me and I walked away with these at bargin basement prices.

So my question is this, I've been looking around for some general specs & pictures on DIY DOVE exhaust porting but I haven't really found anything aside from the basic "Clean up the weird casting bumps for a measurable increase in flow".

I've ported a few sets of small block heads (289/302/351) but this would be my first time tackling a set of DOVEs. I have the general specs that they need to go to to match the SCJ exhaust ports (Exhaust ports are 2.25" x 1.30" rectangular oval port shape) but even the SCJ ports needed some work in order to get a good intake/exhaust flow going.

If anyone has any advice that would be great. I've searched here for articles as well as on 460ford.com but I'm drawing up a blank on the exhaust side.


My goal of this is to build another nice set of heads. I probably wont use them on my current motor as it's already been port matched/balanced and all that good stuff.

I'll probably use these heads on another 460 I'm building that as of now doesn't have a car to go into. :)

thanks guys!

upon getting the heads home and measuring the ports these look like they have some historical porting done to the exhaust sides, the dimensions match at least what the stock CJ/SCJ heads were size wise.

thanks all,

Thank you for the heads up!

Here are a couple pics of the intake/exhaust sides:

Nice thanks for the reply!


These have the big valves in them, I want to say 2.25 intake and about 1.72 exhaust which if memory serves should put them at about the same valve size that the CJ/SCJ ran.

I'd love to see some more pics of your exhaust side work if you wouldn't mind.

thanks again!
