Engine Tech / Building GT40 Heads
Thanks for all the help guys, you gave me a good idea of what I'd be dealing with. And I'm also finding out that with the price of gt40s that aluminum heads may be a better option. Will I have any clearance issues with aluminum heads? I also found these heads on ebay(the link bellow), and I was wondering if anyone has heard anything good about these heads.

Engine Tech / Building GT40 Heads
Hello, I am fairly new at engine building, and I have been considering buying some GT40 heads for my 5.0 bird, but I would like to know the best way to build them. What valves, pushrods, rocker arms, etc. should I use that would be proper for my bird? Would I re-use everything from the stock heads? And are roller rockers a good investment? I want to do a Mid-Output type conversion, maybe eventually a full HO conversion.  Thanks!
