My heads flow 252cfm@.500 lift (intake) 176cfm@.500 lift (exhaust)

I have an XE 236/242 cam.

Would I see a big gain by getting AFR, GTP, or Lingenfelter heads?

 

If you have the money, go for the AFR heads.

 

Keep in mind, the general consensus is that AFR's need some quality porting done to be "worth the money."

 

Yeah, if you get AFRs, save your money on their porting, and have them sent to Lloyd or someone else.

 

Yea Lloyd Elliott is quite popular...he's in Red Oak, TX...

 

This sucks. I just bought a set of AFR LT4 heads.

 

How does the rest of the flow chart look?

You might be surprised as how big #'s does not always mean a good head.

 

$1000?? From AFR?

 

Don't worry man, AFR LT4 heads are some of the best out there. I hope they will work well with the rest of your engine. It is not the individual parts that make a difference, it is the combination of parts. If you can get the right cam, those are killer heads. Porting them makes them even better from what I heard. Good luck.
