head porting?

[jerrad]

is it important to send your heads to a person that ports buick turbo heads only or is porting our heads just like any other set? thanks jerrad

Check out this site. I spoke to them and they seem like they would provide good customer service. I'm sending them a bare set of heads and for $900 shipped to my door they perform the Stage 3 setup.

I've heard that precision porting does really good work. I plan on having my heads done there soon. Here's a thread with some for sale:

i second precisions work. very good. in fact, they are doing my heads.

The heads flow so terrible that just about any port work will be an improvement. I was more concerned about the valves, valvesprings and other components used.

CHAMPION IRONS

DO THE CHAMPION BENEFIT FROM FURTHER WORK AFTER YOU GET THEM FROM CHAMPION?

Wow! I would think that would make a big kick in the pants difference not to mention on the street and dyno. I wonder if anyone has done a before and after dyno run.

I appreciate the information and will be sending my bare heads this week. I may also get their intake at the same time.

What was the turnaround time?

Awesome numbers Tim, cant wait till you get it to the track and get some numbers out of it, i have a feeling 11.teens won't be out of the question if not quicker. If ya wanna borrow my slicks sometime let me know

 

[insane6]

I had a friend take some pic's , I will send them to JD and maybe he can figure out how to post them. Also have the flow numbers before they were ported I will post them.

 

[JDSfastGN]

Wow, the factory heads suck more than I thought. I could of sworn the factory flowed almost 180, but 150 is sad, really sad.

With a 66 cfm gain at .500 lift, that should make for an easy 122 horse gain with some serious boost.

Damn, $900 for 66 cfm sounds very tempting.

And those pistons are really clean.
