Comp XE270S experiences?

Thanks for all the experiences, replies feedback and "get a 318" comments so far!
Vehicle is a '85 D150 32k original mile /6 A833OD trans 3.50 gear 8 1/4 rear. I bought the truck last spring and drove it with the /6 all summer pretty meeger power but very good on fuel consumption.. Over the winter I installed a 30k mile 360 I got from a motorhome put a timing chain, pan and valve cover gaskets and 69 340 avs intake with a 650avs2 carb I dialed in
I have a 75 360 that will be building block for this engine have a set of the Speedmaster aluminum heads and at the time I bought them you got a free airgap knock-off intake probalby going wih the Sealed power 116cp pistons I have a few sets of 273 rockers and bananna grove shafts but would rather find some Isky or Crane 1.5's and probably get a set or Rockets heavy duty shafts I have several different sets of head gaskets to play with to get the quench and compression where I'd like it. Again shooting for a 9.25-9.5 compession ratio I've always been a fan of solid lifter cams in my engines. Thanks again all and FABO
