I think, going by memory, the Indy 440-1 top end set is in the middle 3500 range. Koffels has their sale going on right now and they are close to Indy's price for comparison. The draw back is the pistons and the return oil system. Koffel's even has a dicount going on for moparts members as well as the MC heads.
Thanks to a few members here, I am running a 511 B1 set up. I did not go for the full all out stage port, with all the extra goodies though. It wasnt about the extra price for the MC stuff and Titainium valves, I got the basic kit, with a stage 1 port, since it was my first shot at building an engine with B1 original stuff.
My car with me in it, weighs in under 2800, the power increase for the racing I do, is an absolute blast. Well worth the experience in trying out this combo for the first time.
