I am new to porting out heads. Anyone got any pics of home porting jobs. I need to see how much metal and where to take metal out in a set of 5.3 or 5.7 heads.

 

DO NOT GO BY PICTURES WHEN PORTING HEADS!!!
if i were you id save yourself the time , $$$, and loss of HP, or loss of heads and just go buy a good set from one of our sponsers. jmo.

 

well if you realy wanted to try get a copy of car craft dec. issue and read the head basic art. that might help to get you started.

 

thanks

 

If you want a good head job, you’ll want someone with experience

 

 

ttt for ya. id like to see some advice on home porting also, i have an extra set of heads i want to try and port myself this winter. i know the best way is to send them to a professional, there's no arguing that, but i cannot afford the price of ls1 cylinder heads, and i figure i might be able to do just a simple cleanup on them

 

Look through the forums under "home head porters" or some variation of that. I have a thread that has this info and so does other guys like us. I can also send ya some of my pix, just pm me an e-mail address.

 

I posted cutaways of 6.0 heads not too long back. Not
much material to take away, I believe the flow gain is
more about art than about removal-in-bulk. Also see
some people just hogging away the "swirl ramp" and
others barely touch it; this I guess comes down to
whether these are "street torque heads that flow a
bit better" or "strip screamer heads, below 5000RPM
fuggedaboudit".

No idea how similar or dissimilar the 5.3 and 6.0 are,
aside from the chamber volume.

 

here are some of the pics of the heads i did....

i got them with a RUFF CNC job ... i put about 40 hours in porting, polishing, CC'ing and assembly.

 

you did a really good job. thats about what i want to do.

 

it wasnt hard ... but i did have a PRO watching over my shoulder ....

 

Looks pretty good dude, Kudos to your PRO help.

 

M6 Hugger, did you say those valves were 2.050 and 1.57? Did you change the seats yourself or have them done. Nice work!

 

when i got the heads they were fully assembled .... but with a ruff CNC job....
and yes... 2.05 and i think 1.60?

 

I just got done with a set of 6.0L heads that I had milled .030 and all I really did was just a good cleanup. Just made smooth transitions everwhere I could and took out casting flaws. I found it's really hard to look at a set of ported heads and determine where to take material out. All the research I did lead me to just want to clean mine up and have a very good 3 angle valve job done. You will hurt your performance by going nuts with a grinder if you don't know what you're doing. I just ordered the standard abrasives porting kit and went through and cleaned up the rough areas and casting lines. I have not had the car back to the track since, but none of my porting work seems to have had an adverse affect on the car. I am not expecting huge gains but hope to go a little faster. That's my .02, hope it helps.

 

nice ride there HUGGER!!!! sounds like you did a good job with your heads.....

did you CC, de-burr, and vacum test your heads be fore you installed them????
these are the MOST important things you can do.....
