Whats your budget? You do realize the cost to purchase Edelbrock heads and everything associated with installing them (head bolt kit, pushrods, rocker arms, gaskets...etc) will be around $4000-$5000 alone. These days the cost of rebuilding an entire pontiac engine by doing an actual rebuild with all new pistons....etc and quality machine work is around $9000 for starters. There are places that say they can do it cheaper but you get what you pay for. then there is the wait time of a few months because machine shops are backed up with tons of work.
