Who's ported/polished a renix head w/ good results?

[Mike1331]

I put a HO motor/head in and can't get my renix intake/gasket to line up properly. I've still got a really bad leak at 1,2 and #6 cylinders. So after unbolting my intake exauhst a few times to try and line it up i'm fed up and am just going to put my renix head on. I want to port/polish it first. There's all sort of threads w/ people porting ho heads. Any tips on porting the renix head castings? Will the chevy valves and roller rockers make a difference w/ just a bored tb, intake and exaust, and a stock header?

I just bought the 99+ intake and adapted the tb and the fuel rail from the renix system to fit on the newer intake, also replaced corresponding p/s pump assem pieces. only problem with that is the egr gets dumped.

yeah i'm in cali and have to smog so i cant do that

You can if your Jeep is registered in a "smog upon change of ownership only" county. (=
A good PnP of any head should have decent performance.

I ported the head on my stroker about 8 years ago. Since the rpms are so low, I can't really say it helped that much. The port match to the headers is probably a lot more important.

I port matched a 7120 HO head and my Renix intake to each other with no problems. I used the Renix gasket from Napa.

im thinking of doing that swap to my renix system. what did you do to adapt the tb to the inake. i have tb spacer on mine not sure if that makes any difference in adapting it. whats the deal with the fuel rail? since im in a no emissions county how do block off whatever the egr connects to? im not to familiar yet with the jeep emission. how does your jeep run after you took the egr off? im assuming you have a check engine light on?

thinking about just saying f-it and putting in a reman unit in from these guys 180 for a rebuilt head...way cheaper than i could pay a shop to do it.

Its not too hard to port a head, but it's too damn easy to XXXX it up. Look up port matching, its not that hard to do. If you have time and can wait a few weeks, Ill see if I have a head laying around I can port it and lap the valves and sometime when Im in sac you can get it.
