Urgent, porting advice

Guys my motor is days away from assembly and I am still going back and forth about porting the heads......will it make enough difference to warrant the cost or should I stay away from porting them? If ported, will they cause any long term issues? Looking for some advice please...... I know you 6.0 guys will help

How much are they charging? Actually not sure how a forced induction engine will take to porting (aka. gasket matching). I've ported a 5.9 Cummins once. Figure anything that'll make air flow better is an improvement. One thing I would do, tho, is chamfer the heads (shave/round off any sharp edges), that'll help reduce chances of cracking.

If you'll let me speculate, I'd guess it would help bring down EGT's. If not that, then it'll help turbo response time, quicker spooling. Streamline the exhaust flow out of the engine. It's all about making the engine able to "breathe" better.

That is what I wanted to hear, was will it help the forced reduction. I have heard of ported heads not increasing HP but helping spool up and lower egts, but not alot lower. I thought od porting the exhaust side and intake manifolds will be better. But do I even port the exhaust side. My other way of thinking was this, I am only looking for a high of 550hp. I know alot of trucks out there running 500-550 with out ported heads. So is it worth it............

It's certainly possible to find 500+ HP without doing the head-work. Tho, I'm more the "while you're there" kinda guy. I think it would be more beneficial to gasket-match the exhaust side, but if you do one side you may as well do them both, right? Your call, if you're happy with 550hp I'd leave it alone since I doubt you'd see the performance you'd want for the $ it would take to do this.

just remember if you decide to port the heads yourself, this isn't a gas motor, you don't want that rough look to the ports, smoother the better, all that's flowing thru that head is air, not fuel like a gas motor. We dont need to help the mixture of fuel and air in this situation. Best of luck and porting the heads is never a bad idea, i would gasket match everything too while your at it.

I vote to port them. Not gonna cause any damage to the heads. Only going to make performance improvements. At least port to match gaskets.

you know there is a difference in "porting" and "gasket matching". Porting involves getting the entire port.. Gasket matching is just opening up the end of the ports the match the gasket size then tapered into the rest of the port

For my money I wouldn't bother for 550hp. I'd run a gogo intake which is a major restriction and will give you a good gain in flow. You can gasket match yourself and if I had lots of time on my hands I might consider that but there is very little to be gained by it. A Powermax with a Batmowheel and 190's will give you close to 600 hp without breaking a sweat, especially with a gogo intake.
