I did it, and its a blast. Its not really hard and its pretty cheap too. The info I found some great info on some sites but I'm on my work comp right now so I'll post them when I get home. The intake isnt that hard and you have 2 choices.
www.pricemotorsports.com which has adapters to mount any intake you can think of to a clevor headed windsor, or this other site, again I need to get the name, but they have the original B&A intakes brand new. They run about $450 and they have both the Track and Street Boss intakes. That site shows you how to modify the heads but basically the larger water hole on the surface of the heads needs to get drilled out so you have fit a freeze plug in it. Then you drill a hole on the intake side so that water will run through the intake instead of back into the head since Clevelands dont originally have a provision to push water through the intake like Windsors. There are some new steam holes that need to be drilled out too, and as for the pushrods just use a checker to see what you need since you should do that with any head change project. Hope this helps out. If your doing a 302-351 use the 2V heads, but use 4V's for the windsor strokers with a 392 or 408. I have 4V heads on a 427 stroker and it works great because the engine is large enough to use those runners.
