Burnouts - What's the problem?

hmmmm probably torque converter is stockie and 6 pack bogging

if it was me... you *** could *** replace the top end while engine is in car, but...

you would be best off leaving it as is driving for now, build one with a single plane, 10:1 compression, 4bbl double pumper. get a converter ready.

it would be easier in the long run. the eddy heads will require some blueprinting work to make it right. you could just bolt them on and go but it will be better with adjustable rockers (suggested in their install docs) and cut-to-length pushrods. but making the top end nice without fixing the compression is not optimal.

for compression you can go 10:1 on super unleaded, but *** if *** E85 is readily available in your area you can go 12:1, which will give you amazing power and allow for bigger cams like a .590 . however, finding E85 pumps can tie your car down if it's a street car.

i'd find a nice 360 or 340 core to build up. save your money plan & swap it in when you are ready. it takes a long time so keeping your car intact for now is just what i would do. that way you can enjoy the ride while you are planning/building
