Description:

Up for sale is a beautiful set of 243 heads. Complete and assembled (minus rocker arms and pedestals) with TSP .660 polished dual spring kit with PAC valve springs and titanium retainers and valve seals. Heads have less than 1,000 miles on a refresh which included a skim resurface, valve seat cleaning, hot tanked, valve guide hone and pressure tested. Bolt on and go set of heads. Both steam ports have been opened up. Only selling because I moved up to a set of ported heads. Bolting these on a LS1 engine are a great way to add 15-20rwhp and flatten the torque curve and up compression from the stock 241 or 853 heads while be able to run a much more aggressive cam with higher lift/duration without worrying about breaking springs. $600 shipped.
