I have windsor jrs to replace my E7 heads for now but I plan to upgrade and rebuild my short block with dished pistons sooner or later. Staying with the budget brawler theme, patriot performance's heads seem to be right up my alley. They offer good flow numbers etc and all that is great on paper, but does anyone have any real world experience with these heads? My mech says to stay away but he's a AFR and RHS dealer...
