Complete LS1 243 heads ?

[Paraman1]

I have a set of 243 casting heads with all new valves , Texas Speed 650 lift valve springs and the Comp Cams Trunnion upgrade kit. The springs and valves have 1000 miles on them at most . Just curious what the value of these would be ?

I'd say around $550-600 on the heads with springs and around $150 on the rockers w/trunions.

4-5 years ago, the LS6 heads were a hot ticket, but now that the square port engines are more and more available, I see the cathedral heads going down in demand.

I feel $500 for all of it is fair. If they were ported or larger valved heads, they would be more valued.

I have seen used 243/799 heads sell for $250-$350 on eBay all the time,
