been available for a while,these were a good deal,too good to tell. the cnc flow # are 511in-350ex w/o pipe.2.5 intake valve,1.880ex. i will flow these when i get my valves from uncle charlie and we'll see what they do.they should have been 85cc's but they were 100cc's,so who know's what they'll flow.

I'm surprised they are only 10 bolt heads.

You musta got confused...aint no porn in here, just some pictures of some cyl heads.................

pistons have sure been tuff to get.the valve size and chamber shape are not the usual,BUT Lem is on the case so i'm sure it'll happen soon.he's already sent me most of the parts to put it together,and he will call you back too hell of a good guy.

Just north of the 'Bama state line,,,,

Nice heads! Your blueprint sheets are done, and custom titanium Victory 1 valves have been ordered.

Never mind, checked out the website and found most of the answers to my questions. Which intake valve are you going to run, the 2.450" or the 2.500"?

Which valve cover do the take, I thought I counted eight mount points in the picture. Also, do the standard TFS intakes work? I tried to call the today, no answer....

2.500 intake valve 1.88 exhaust All A460 stuff will fit,

10-4 Blake. I might have to try a set when I get my other issues straightened out.....

I have a set with the 2.450 intake and 1.880 exhaust.

Curious as to how Lee's will run.

we gona see what they do on a 572.4.625x4.250 with all the compression Lem can get diamond to put in the hole!Blake's got the cam spec's in his head somewhere,much as i'v bugged him he may keep it.

so does stock a460 valvetrain work or do you have to custom rockers? Different length push rods?

From what I read on their website, all the A460 stuff is interchangeable. I'm impressed by the flow numbers if they are accurate....

the push rods i dont know about yet,the rest is same as a460.the deal with the valves bee'n so big,as Lem said "big as a cows ass",they get heavy and heavy dont like high rpm.these heads are high rpm or big inch so ti valves are a must or it's a waste.at about the same point the shaft rockers start to look like a good idea too but i'm gona run the crower's for now and see what happens.

I wonder what's the most you could mill them down if you wanted to and what an angle mill would do?

I'd be interested in the flow numbers, I have two friends working on 582's (one for sure the other might do a 565) I told them about the IDT heads. I wonder if they flow what they advertise? Hope so, but I know a guy who flowed a set some years back.........

Hope yours flow as advertised.

I would realy put a set of shaft rockers on them. There is not much difference between studs/ rockers and girdle or a good set of shaft mounted. But the shaft mounted are much better.
How much lift and seat pressure are you going to run?

i dont know what the open psi will be but seat should be 280-300 @ 2.100.the springs are manley green's from Lem.

If/when a guy had an A460 cyl head designed for a shaft rocker deal it'd be cool ......I aint seen one yet.
