Cylinder Head Work?

I have a set if Edelbrock RPM heads on my car now which is part of a shortblock HCI swap. I'm thinking about pulling the heads and sending them out to have work done. So my question is what's the most work I can do to the heads to get ever once of HP out of them ?

The Edels are not very good candidates for porting, there isn't TOO much a good porter is going to be able to get out of them. Better option is to sell them and pick up a set of higher flowing heads. What sort of bottom end are you working with?

Call TEA or Fox Lake and see if they can do something on those heads and what it would cost to see if it is worth the trouble and time. Porting ain't cheap.

Its probably cheaper to just buy some new 190 or 205cc heads depending on what bottom he has. I mean the Eddy RPM heads only flow like 230cfm at max lift and that's for the 2.02 intake valve jobs. TFS TW170s flow damn near 260 right out of the box and then go up from there to 190 and then 205/225 depending on the app.

I agree Scotty.


That is why I tell people to call and see what they charge......that's why I say porting ain't cheap. You need to get someone who know what he is porting as all heads are different and each one like their own special way.


There is disassembly, reassembly, inspection and replacement cost. You might find someone locally who can do some minor clean up but to port correctly you gotta know what to open up, drop down, reshape, radius where.......the list goes on.


Sorry to be a Debbie Downer today ugh.

Are you doing like... a full build or just a HCI on what you have already? Its a 306 IIRC right?

Gotta look at the big picture when doing a build.


So you better flowing heads.....well you are gonna need a better suited cam to take advantage of the air and rpm band which will also depend on the intake.


Making power is like getting a dysfunctional family to work together correctly.

Hmmm, what I would do:

-TFS 190cc heads or AFR 185s
-Custom cam from FTI (FlowTech Induction)
-Call up Freakshow in Abeline, TX and get a better converter or just bite the bullet and get a PI Stallion.
-Upgrade to a Performer RPM II intake
-New tune obviously

Ed Curtis at FTI can probably set you up with a new HCI that will be optimal for what you want to do, I'd give him a call/shoot him an email.

Just to give ya an example there is a guy I know who runs TW 170's cleaned up with some work but not hogged out or ported to the max with a custom FTI cam and a Holley intake on a well built 306 and put down a hair over 330 to the tire with just a tad over 330 torque.


You have a healthy combo but if you want more power it is not really worth a whole tear down. Get a used Vortec, Paxton or Procharger.

Remember, he is an auto so dyno numbers will be down vs a stick with the same combo. However, 1/4 times (which actually matter) will be quicker with the auto.


I mean I put down 325wtq with the same Eddy RPM heads and a megabudget cheap 302 rebuild.


Seems like a dedicated 1/4 car from his pics anyway so he probably should just throw a 175 shot at it and call it good. Stock block won't take much more than that anyway.

Ok need a little more info .... Was checking out the On3 Turbo for 94-95 for $1,500. I'm sure there are tons of threads about this but I'm gonna ask again. I have a stock block with brand new internals but the are NOT forged internals. With what I have mods wise and on a safe dyno tune, with my motor hold up ?

I don't beat on the car at all , I don't race it and it's never been on the track

Internals are not the weak point on a pushrod, the block is. 450 is safe, 500 is pushing it but you may get away with it if you don't beat on the car much. Any girdles or screw in freeze plugs or anything like that is worthless.

The On3 kit is indeed from China and there were some issues when they were first made. However... Chad (the owner) was VERY proactive about making sure the quality was there and they have been very good products in recent years. Guys run 9s on box stock On3 kits in Coyote land, I would not hesitate to buy the On3 kit and run it on anything.


FYI, a lot of turbo stuff is made in China, the On3 turbos are actually "generics" made at the same factory as some of the "big name" ones.


I HATE how everything is made in China these days... its going to bite us in the *** eventually but its the world we live in currently... oh well.

They are running 8's with the off the shelf on3 kit now. There is a few of them.

And the turbos are actually built on the same production line as the magnum turbos.

Yep, I couldn't think of the name of the turbos they were "generics" of and I was too lazy to go to the On3 site or the Corral thread to figure it out. I know the Coyote kits did get updated with a better inlet/outlet on the intercoolers and a few other things. Its nucking futs how fast the Coyotes are going with these twin kits. Those are the 67mm upgraded ones IIRC.
