Default 241 Heads - mildly ported and milled, dual springs

Category: Engine - Intake/Fuel
Price: $500
Location (State): IN
Item Condition: Used
Shipping Information: Item Can be Shipped
Engine: LS2/LS3/LS7/L92/LS9, LS1/LS6
LS Engine?: Fits LS Engine

This is a nice pair of 241 heads. Mildly ported. Milled to 61 cc chambers. 3 angle valve job. Dual Trick Flow springs. 3k miles since freshened up. These heads work very well. No flow sheets. Machine work by Quickie out of Winimac IN.

Removed these heads for my boost build. The price is less than I paid the machine shop to do the work. lol Ready to get these out of my way.

Stingy Dyno'd at 416/410

Went mid 11's@120 in almost full weight 4th gen N/A and 10.30@131 on a 150 shot.

Pictures of port work were before they were finished

Some interest but not serious enough to step up to the plate I guess. How cheap do I have to sell these things? Or is someone interested in just the springs and I will separate. Low miles!

Ppl get bent out of shape on the number! "243 are better" the 241 head is very capable head and can produce some numbers down the track! Free bump for a good guy!

What is the max lift on the springs? I don't need the heads but I need some high lift springs.
