I'm not sure what valves and port work will cost you but if I had to guess you'll be looking at $700-$1000 roughly when your heads are done, close to the same for edelbrock heads. Then roughly $500 for a new carb.
Maybe if you get a set of used assembled edelbrock heads and don't bother having them checked out by a machine shop. And it's possible to get used or cheaper new carbs for $300 or less if you know where to look.
Guys pay attention to the man's posts he already said multiple times "I will get the tuning sorted out first and then look at other upgrades" maybe it's just me but it's incredibly annoying when people tell me to do something I already said I was doing :banghead:
