Dawg,
Your right 10 to 1 corrected is the way to go, but the problem is they havent set him up with a quality / value package its more of the slap it together inexpensive way to go. They are giving him cast pistons over forged they are giving him the cheapest heads which have absolutely no QC on them as pairs. I have seen one head be great and the other so bad my stock were better.
I recommended to him to buy 5 over pistons / rings and then have the cylinders honed to get the tightest fitment he could based on tolerances / clearances. Tommy understood how important break in would be if he goes on the tight side of a build. He is considering the following cams S&S 585, Andrews 60g, and Zippers 570g. He is going 10.5 to 1 using a cometic .030 vs harley .050 or .060. The issue is deciding whether to have his heads done or buy HTCC or other as well as they were giving him stock lifters instead of SE Lifters and so on and so on.
Tommy is a bit more educated tonight and is going to go revisit the dealer to have a more indepth discussion about what his specific wants are now and the combinations open to him. Hopefully the shop he is dealing with will treat him well and understand what he wants / needs to keep reliability and get the most bang for his dollar. If he wants more help I am sure we can put together a proper parts list for him by sku number and let him revisit the dealer again. I don't think that is going to be necessary as he has a pretty good handle on the pitfalls infront of him if he leaves it up to them to interpret what he wants.
