vonrottes Posted September 9, 2016 Report Share Posted September 9, 2016 found a set of 799 heads from a 2005 Trailblazer with a L33 5.3 shouldn't be more than about $150 for the set, intake ports on one and three had standing water, oil inside the valve cover looked tar. For the price would they be worth getting if the chambers look good? Machine work will be needed before they go on my LM7 so... it's fine if they need a little work.

Cordell Posted September 10, 2016 Report Share Posted September 10, 2016 799 is the same as a 243, and are as good as you'll get for the cathedral intake port. Under $200 is a good deal imho, send them somewhere to be ported and you have about the best you can do with a stock casting. Quote Link to comment Share on other sites More sharing options...
