LSA/LS9 heads?? Have any of yall ever used these head with big boost? I think they would be bad ***. with the way there casted as well as i have read they have a thicker deck.? any info ? or am i going to have to be the ginny pig 
They have about a 3/4" deck and ports are nearly identical to L92/LS3, except for a little casting in the intake runner to swirl the supercharged air.. I plan on running them as soon as possible, although i'll cut out the little blip in the runner.

They are 68cc as cast, but can be worked on to get a bigger cc. They are a high-strength casting made of A356T6 alloy, for greater heat resistance, manufactured using the roto-casting method (like the LS9 heads) to virtually eliminate porosity.
They are a great head for turbo!!! I plan on making upwards of 1000whp with mine.
Here are mine after I had them hand ported. We took out most of the swirl wing, but left just a bit to help with atomization.

does anyone know what the minimum bore size needed to run these is? and i hadn't heard anything about it being a 3/4" deck but definitely the better alloy. Would love to get deck thickness confirmation as well.
