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:

I finally got them home and am happy with them so far! They will have to sit for awhile till I have funds to build them. :(

Great to see they made it home with you. There is an incredible amount of material in the runners, if you can feel down the intake runner and in a pinching hold, feel how thick the roof of runner is to the valve spring seat area, those heads have plenty of potential :2thumbs: when the time comes, you can play then.

Ya I see what you mean! Feels like 3/8 or so! I'm going to go with the longest valve that fit to take full advantage of that too. I was looking at Comp Cams beehive springs?
I brought them to a buddy of mine who builds race car engines and he was drooling too. He can't wait to get started! We sat down and figured out some of the math from an old pair of 915 cast iron heads he has laying around. I am responsible for drill and reaming the valve locations to 11/32 and he will do the rest. At this point I don't think I'll go with the 2.250 " intake valve. This will be just a street engine and I'm assuming it will make more power than the tires/chassis can handle anyhow. These came with all the seats and guides although they are for 3/8 valves I most likely will use them. Lots of valve  brand choices!
 Lots of burrs to remove but that's expected.
Thanks for putting me onto these Kenny! :2thumbs:

The outlay for the guides is not all that expensive, go with the 11/32, you will be better off this way. I gave my set of 3/8 guides to Alan, as they were no use to me for what i had planned.
There is a multitude of potential, take full advantage even with a smaller valve, remember to locate the intake valve in the best location with enough room to go larger for a future overhaul if the oppertunity arrises Brad :2thumbs: i would be interested in measurements and progress as you go with yours if you did not mind sharing the info please :wave:
