Dunno, it MIGHT be 64, if you look at it long enough and that would make a little more sense. Especially if they put the large valves in the 15. But why not finish the job with screw in studs? Unless the 1 photo was taken mid-build prior to studs? You might be able to see through the holes in the valve cover if one, both or none have screw in studs. A 62 would have screw in studs for sure. Attached is a pic of a 64 I swiped from ebay, apologies.

Dam, missed that it is a 455 Crank, and in the lifter valley it looks like it may be a 8 cast in there?

Yes 64 heads castings have screw in rocker studs.

What would be the best heads to get for my engine on a budget build?

I used a stock set of 48s with dished pistons for 9.5 CR.I think any big valve heads with screwin studs could work with dish pistons.There are other heads with bigger chambers that would also work.Tom

What Is considered big valve? I have seen a bunch of redone 6x and 4x heads on ebay

I've got a single 62, well another I was playing at porting but hit water and a pair of take off 15s from a 70 Bonneville -block is in my 78 TA. But they are heavy to ship.

Head wise it greatly depends on if your buying a set of rebuilt iron heads ready to slap on, of if you will need to send them out for work before you bolt them on, and even initially what the shipping cost would be to just get them in your hands which is not cheap!

You very well might find that you could come within 300 bucks of just buying a new aftermarket D port head when you run the numbers.

Iron head wise my first pick would be a set of -4 or 4H heads from the 4X casting line of heads, or the 5 serise of heads with screw in studs, or a 6X casting, and all of these like I posted should have the 4 stamping to provide the compression your looking for to get into the 9 to 1 range without having to mill them but for a .002" clean up.

Other iron head casting numbers you maybe able to turn up would be 1971 # 96, 1972 7K3, 7H1

This all assumes that the motor has not been built with dished Pistons of course!

Before this head search goes much further... Need to figure out if the ten year old pics are of the engine that's in the car now.

Has it got a 455 or has it got a 400 that the OP was told that it had?

If it were me I'd go and pull the heads and get some better pics to verify. A couple pics of piston tops will tell us if the pistons are dished. You could also verify engine size if all else fails by measuring piston travel. These steps will go a long way in determining what heads will be your best options.
You said that $ is an issue. At this point( after pulling the heads) you can decide weather the engine will be pulled. It all depends what you want to do with the thing. Those heads you show look like they've been on there for a long time. Any idea how many miles? With two different heads on that thing the whole rebuild may be suspect. Again... your call. Larry

I'm going to get the block casting and the other heads casting number this weekend. The motor runs fine, has taken me on numerous 1hr+ rides to and from Atlanta. It's just not what I'd like to be doing performance wise

People wouldn't be resorting to guesswork if you wire brush the rust off the center ports and take a decent pic of each head.

So I got a chance to go through the things, car has matching 62 heads on it and is a 455.
Are 62 heads worth having gone through (finding a machine shop to do it will also be a hassle around here) or just buy a set of 6x from nitemare performance for about 1500$

Also odly enough car has a 3.42 coded rear end but when I jacked the car up and spin the tires to count revolutions in the drive shaft its about a 2.56 or somewhere in there gear. Which now Im thinking is the reason behind my sluggish takeoffs

Can you pop the valve cover on the other side and shoot a pic of that?

Obviously the cylinder head picture posted in the beginning of the thread is different from the last couple of pictures of the 'other' head with the easily seen screw in rocker studs and rockers.

So I need some info on exactly what you are asking for in this thread.

The car is a turd should be way more grunt to it than what it is. Now seeing I have pretty decent stuff as far as heads and manifolds I'm thinking my problem is more in the rear end and carburetor
