Like title says bare heads need valves and springs (2.055 - 1.57). I bought these and now my plans have changed. $425 shipped. The guy I bought them from said Patriot quoted him around $400 dollars to get them all good to go.

whats the chamber size and why do they need new valves?

 

64cc and just because they don't have any.

 

Sale pending.

 

If the sale falls through, let me know.

 

those are the older style 6.0L heads not LS6's FYI good luck with the sale bump for a good deal
