Well here is a quick lesson for ya....you can bolt on any of those big flowing big power capable heads on a stock block platform....for example W5 W8 W9 guess a person should include the Indy 360-1 and -2 stuff BUT you will have significant issues making it work with 59 degree block and the heads that are 48 degree and in general you will be grossly overpowering the reliability of a stock block platform if you try and even come close to full potential of these heads mentioned. Stock block you run upwards of 600 hp with good machine work and combo and tuning and keep your fingers crossed and if you want more than that you can easily obtain it but you are now into big boy deep water and will need to be utilizing a race block platform to use real cylinder heads, especially the W8'S and W9'S.....like I said before it comes down to what you can afford or what you are willing to spend and also your intentions.....you have stated none of those.
