Looks pretty good. The 108 LSA will give you the noticable idle you want and the 221 @ 050 will build some cylinder presure. If you are squeezing the buget and not the horsepower/torqure to the limit I have built some budget engines using house brand cams from Summit and Jegs. You could probably find a close match and save a couple dollars. I would not cheap out on Lifters though. The foreign imports for half price just don't have the tolerance control to make a decent product IMO. I am also a fan of pushing the valve lift with rocker ratio like 1.6. A great rocker with a good price that is not talked about much is Scorpion brand

They always seem to come up short which cuts back on valve lift and some duration. I prefer to order my push rods last to set up the valve train geometry. Stock length never seems to be correct with a mix of parts and machining. Adjustable set up push rods are cheep and worth the time and hassle to get the rocker to ride in the middle of the valve stem like it should.
