I am selling my GM Performance Parts Fast Burn heads that are fully ported and flow bench tested. They have been used for approx. 500 street miles and 30-40 1/8th mile passes. I have gone up in Cubic inch and need more head. They have 2.05/1.60 Ferrea 5000 series valves with new springs/retainers etc. All hardware included except new seals. They are disassembled and will require a light mill to clean up gasket impressions. They have not been milled or hurt ever. Combustion chamber is 64cc and intakes measure 220. Heads were flowed on very conservative bench and went 279cfm at .600 and 287cfm at .700 with strong numbers through low and mid range. Some intake runners have epoxy at push rod pinch used to achieve CSA for good flow. 83 Camaro in full street trim on straight pump gas, with solid roller small enough to run power brakes with no assist at 406ci went 6.90 1/8th mile with 3000 stall nitrous converter N/A. Also with heads you will get a Super Victor intake and Perf RPM intake port matched to heads. $1000 for all. I do not have pics at this time but am working on it. BTW...In case your wondering, these heads bone stock only flowed 248cfm on the intake and the exhaust was horrible at only 155 cfm!! Call after 5PM for questions. Houston TX area. 281-389-6150

Whats your cubic inch? If it is a 350+, you will be fine, don't think it would work for a 305ci. I have springs for a HYd roller and street solid roller. Intake valve is 2.05, intake runners are 220cc and have lots of velocity for good low and mid range cfm. Combustion chambers are obviously pretty good. I was running 11.6:1 compression on pump gas and timing locked out at 36 degrees.

Looking for a victor

This intake has been ported to match these heads and would not likely work for your application without epoxy or welding. My runners are raised and widened over the stock location. Do you need one for Vortec or standard bolt pattern? I have another Super Victor that is for standard bolt pattern and has been modified to bolt to Vortec heads. Runners have just been cleaned up near gasket surface. Let me know if you can use it. $100+ shipping.
