The guides were ok iirc, small correcting of the seats

And there's no way those 516's are only needing to be cut for the 1.74's. I own a set of stealths and I chose to have Dwayne correct the vj and port them a little, but those weren't mandatory steps.

Stealth heads are $1400 for the pair and would make a huge difference in performance. Even if you 'only' had to spend the $900 to get your 516's serviceable imo you should find the other $500 in your project budget. No single other expense would bring as much benefit.

depending on how long a wandering road you go down, yes it might be just as cost effective.

Yes, I have had 1 set of 516's near that and they were heavily milled. Another set was milled some and still only 78cc Dwayne's numbers are very valuable yes.

We're entering pissing match territory but plenty of real world tests show what people on this board consider 'race' parts generally help at lower rpms and more street life situations than they realize. The compression difference depends on the specific castings. The low and mid lift flow...

Like I said, I've never read a single dyno pull or time slip that showed a bb head with a 1.60 valve performed better at any rpm or even 60'. Would be interested to see it. Your car having acceptable performance in no way means it wouldn't be faster with 906 heads on it. I'll bet a dollar it...

I agree on the cc's having measured myself. I'd like to see dyno results showing a 1.6 valve ever helps anything. BB heads are really sized for 361-383 engines. The max wedge head should have been standard on 440's, hp's at least.

Lots of opinions probably but I don't use that fiber but do use some rtv

I also wouldn't be too worried about the current oil and rather than mix additives going forward just use VR1

How deep do you want to get into it? Those early 383's can be woken up with intake and headers. Like was said before, it's got a baby cam. The heads are also pretty poor. A lopo 440 is going to suffer from it's own shortcomings

Photos?

Center dump like that would be very difficult to bolt a pipe to even if the header itself fit. K member interference likely.

Those look like truck headers to me, very long before the curve

I'm guessing he used a whiplash style cam?

Then the lead build up is already gone!

I missed the first post, what was the issue that caused you to pull them off? Go to moparts.com tech archive and read Dwayne Porters posts about OEM heads and all levels of work to them and the gains. Make a data driven decision then. My 2 cents having had various OEM heads including 516's...

Holley now makes kits for a/b/e that might give inspiration as well

Tranztech in Dubuque Iowa did it. I'm not sure if he made a C body template for reuse. He mostly puts them in a/b/e

Also anyone with floor shift the od interferes with the down shaft. I converted the OEM shifter to use a cable
