I recently bought a reman LS1 engine off of ebay and im going to be putting it in my 06 silverado, just wondering what heads i should go with? i have a set of 317s at my house, just wondering if i should go with those heads or some 243s? and if ya'll recommend 243s then anybody got a set in houston for sale or maybe want to trade em for my 317s? thx fellas

 

243's all the way man,m buy some ported ones if you can
