Okay guys I am going to be selling my current heads off my lt1. They are stock with a really great port job. They have the comp springs that have been set up for use with the 306 cam. They still have the stock size valves.These heads on a 383 with the cam have ran a best of 11.4 on motor with 6 speed and 11.6 on motor with auto. They have gone 10.7 with 150 shot of nitrous with auto. Ihave no times with nitrous and 6 speed. I do not have a complete flow sheet on these heads. I didn't want to spend the extra money to have the whole heads flowed. I did have the speed shop flow one intake and exhaust side. they flowed 242/196to 98 can't hardley remember the exhaust. I know that these aren't the most impressive numbers but the heads do run really good anyway. Also one might like to know that these numbers are with a dual plane gm intake and carb so these heads might pick up with a good Efi intake. I am wanting to upgrade heads and go faster this is the only reason I am looking to sell. The heads are still on my car so if you lived close enough you could come down and seem them in action first hand. The heads also have guide plates. I would like to have 1000.00 shipped for the heads.After the heads sell I would let the cam go for 150.00. But I am not going to tear her down untill I have a buyer for the heads.

 

I'll be first in line for cam if the heads go.

 

Okay old 93z you have first dibs on the cam. Now doesn't anyone have some new christmas money thats buring their pockets and needs some good heads
