- Has anyone tried the EXTRUDEhome process to port/polish the heads?
- This process uses an abrasive paste under pressure instead of a grinder
- to alter the shape of the ports. The add I saw claimed about 25% increase
- in flow over stock.
-
- Does this process REALLY work? Are there any dangers (does it open up the
- ports to much or damage the valve seats)?
-
- Would an experienced tuner be able to do a better or comparable job?
-
- Thanks in advance,

- RF.
