Pete, suprised you didn't mention AFR heads.. :) The best head for a Windsor by far.. But for a limited budget the P's are the way to go, i'm porting my own. I'm mainly doing the exhaust side (deleting emissions bump, smothing valve guide boss etc). I don't really want to touch the inlet besides the bowl area. If anyone knows a good company that can fit a larger intake valve to the p head in the Central Coast/Sydney area please let me know. I thought the spark plug boss has to be cut down in the chamber to clear a larger valve but the stroked T series head doesnt look like this was done.
