The stg 2.5 5.3l heads should have tons of results in the dyno section. We typically build them with 2.02 intake valves & a 1.57 exhaust valve. I'm currently working on a 2.055/1.60 valve setup for those cylinder heads that will be available in the next week or so! Look for bigger flow on both intake & exhaust, but at the expense of some p/v.
I'll have some additional information very shortly!

Mine were shipped out Wensday I'm told. I was reccomended the 233/238 cam. I wish I wouldve gone with the MS3. Flycutting isnt a option so I couldnt do MS4. I look foward to them.
