You can do very well with the Edelbrock heads. Engine wise, after a solid short block, the heads/valve train is where you spend your money.
A better header is always a good bet but depending on your target goal, you can skimp on headers and still be OK. The average 1-5/8 header can take you pretty far. I know they suck for installation and ground clearance but there cheap by comparison to TTI. And a simple Jegs/Summit exhaust kit (with or without mufflers) and a “H” pipe is an easy install well worth the price and effort.
The biggest problem with the header companies is quality control IMO. Not to mention no design update on the ill fitting 50 year old design that has 3 tubes under the steering linkage that has to come apart to install the headers. Super annoying!
This is where TTI and Doug’s headers come into play as a favorite. And at a price.
As of right now, just get your short block squared away righteously. Worry about the rest later. No sense putting the horse before the car. Once your short block is done, then you proceed to the next thing on the list. Knock’em down one at a time.
