Most economical Ported Head

[CTX-SLPR]

Howdy,

Budget is way tight with me since I still have injectors, a Ballbearing GT-wheeled turbo and 600hp TH200-4R tranny to buy not to mention many other little items. Who sells the best ported heads for the money and who has the cheapest set of decent ones?
I know this is a rather subjective question but a set of stock irons would realy, really choke my otherwise heavily worked engine. I'd also open to used ones, though they would have to be ready to rock except for coverting over to roller springs and such or maybe a valve job to fit my on the shelf big valves.

All advice greatly appreciated. Thanks,

Best? CNC ported GN1's probably. Then unported GN1's. Then Champion ported irons, and so on. Best to go with a porter who understands fluid dynamics. Not someone who just hogs a port out. Here are the numbers I got out of my cobra heads, without opening up the cross sectional area more than 1/8".
Intake port before- 28"...216cfm @ .500. Low lift numbers not so great.
After- 28"
.100- 100 CFM
.200- 183
.300- 242
.400- 293
.500- 297
Exhaust improvements were just as good. I was able to make some serious gains, especially at low lifts by doing an intelligent port job. By not hogging the ports out, I was able to keep velocity high at the same time.
Find a shop that knows how to do this. Concentrate on the upper roof, the pocket and the back of the valves. Increase high lift flow without hurting low lift flow and velocity. Find heads that give you the highest average flow across the board. Not some meaningless high lift peak number. These are the things you should ask the porter about. If he doesnt understand what you're saying, run!
Fox Lake does very very good work.

Thanks, but Champion Irons are about as expensive as I can afford and only after about 2.5 months of saving for them. I was hoping for a bit better balance of dollars spent to performance gained. This car will live mostly on the street, never go over 5500rpm and is running a Comp Cams 212/212 roller with 1.65:1 roller rockers. I really don't need a race head, just something thats not going to choke down my engine. Right now I have a set of 8445's and some bigger stainless steel valves so a good company that could take my existing pieces and port the heads and add the vavles and springs and such would be a big help aswell.

Anymore help is gladly welcomed,

A set of fully ported champion irons are only 1199 and I think its 175 for the port matched intake. You probably wont save any money by having yours ported and they wont be ported as good as the champions.

I would definitely go this route if I were on a tight budget( I should be)

You will have a tough time beating that price of $675 and the parts it comes with the Stage 2 port work. I went with the stage 3 and they flow more than Champion irons and just about 10 cfm under out of the box GN1s for $950. I also had him do an intake for me as well matched to Felpro 1200 gaskets.

Tony is a very nice guy to talk to and the port and bowl work are as smooth as glass. I have pictures of the heads and flow sheet numbers if you are thinking of going that route. I would have loved to have gone with P&P GN1s, but the 2K+ price it would have cost to not be shooting for 8s turned me away. Guys on this board have been 9s in the 140s with ported irons.
