The ONLY real stage 6's are the chapmans....... the rest is a crapshoot like 440source stuff.........  :2cents:

Issue with the castings and the roofs are real thin and makes the spring pockets real weak...

Well I pulled the trigger on the semi finished stage 6 heads on E-Bay!
1Bad Mopar I hear what you are saying about the spring pockets, that's why the semi finished heads are what I went for. I can get longer valves from Manley and not cut the spring pockets so deep! Manley makes them for the Indy heads! 5.344" long instead of 4.870"!
This also should allow me to port the roof higher too! :thumbsup:
Can't wait to get them and start machining them!! Handy to have a mill in the garage some days!

Great going Brad, Keep us posted as you do different things with the heads and what ideas you have when it comes time to machine them buddy. :2thumbs:
