So I've had problems off and on with my car and finally found the culprit. My heads are leaking oil and fouling out the plugs BAD!!! It still runs, just very poorly. I know I could just put a couple bucks into the 915 heads, but with dad just putting together a new motor, I gotta keep up with his.
Current stat 1968 Super Bee
383 bored .040 over around 9.5-10:1 compression. (checked compression and its 145-155 in each cylinder )
Heres all the info on the box (don't know where the little card is)
PBM
150118
Adv. Dur. .050 Dur
Int 284 218
Exh 284 218
Valve Lift Int. .458 exh .458
Lobe Sep. 110
Performer 383 intake, 750 holley vacuum secondaries, stock hp manifolds, 3.55 gears, 295/50/15's on back
The heads are just redone to run w/ new gas, x angle valve job (nothing fancy at all).
It is a street car as I've got 20,000 miles on it since 2006 and it will stay that way.

The bottom end is all good. Should I just fix the heads (cheap) and put it back together
. Or get a pair of new heads and cam?

The exhaust manifolds are probably here to stay also. Stealth heads and..... or ?
Also an option would be stick with the same cam but get better heads, but I've been told the cam isn't much more than a stock one. My dad just had his heads redone and beefed up, but the amount of money spent would just buy me some brand new ones.
Done rambling, what should I do?

if you want to beat him get new heads. eddy or stealth but have a shop or someone good with heads take them apart and go through them.
or just fix the oil leak. usually a 509 cam is suspose to fit (purple shaft. or see if the 528 solid purple shaft fits.

If you pop for some good aluminum heads you might as well ditch the wimpy cam and intake. A good set of headers wouldnt hurt either. I think You might be optimistic with the 9 or 10 to 1 compression ratio. Some reworked stockers with a gasket match and pocket blending might be the way to go with your current combo. Just keep in mind that an engine is an air pump. The more you can get in AND out the better it will run. It takes more than good heads for an engine to really perform.

I'm gonna keep an eye out for new combos. I would love to build a stroker, but my motor is essentially in good shape. A local mopar club is having a dyno day that I'm planning on attending. I'll try to get my dad to bring his too.
