engine tech vortec heads
Anyone ever use these? They have bare castings on rockauto cheap. I have everything I need (springs, valves, rockers, intake, etc) to install these on an engine I am building up. I purchased a set of used heads only to find that they both were cracked. After talking to my machine shop they tell me that is common. Oh well, lesson learned I guess. The GM heads seem to only come with springs/valves installed. My machinist tells me he has had good luck with aftermarket iron castings even though they are made oversees. Thanks,
Bill
