So I got a bored 347 and plan on putting some aluminum edelbrock heads on it. The heads are edelbrock performer and have EOD-215-33 written on them. The heads were used so i took them to a local machine shop. The machine shop called me and said they need new valves, but they have no idea how to get valves for edelbrock heads. So I was wondering if anyone knew what valves I need to buy. Also, the cam in the 347 has a 555 lift and will need stronger springs. So i need to know where to get stronger springs for those heads. The machine shop isn't much help.

 

number 1, if a machine shop has no clue where to get valves for eddy heads, run!!! and run now, take your stuff and find a different machine shop, for one eddy heads such as the performers have 1.90/1.60 valves or a 2.02/ 1.60 and without looking your part number up it's one of the two....and number 2 if a machine shop can't make a recommendation for springs, then definitely run from them!! we need to know more of the specs on the cam...part number???

 

Yea I was getting the same feeling. Thanks for the advice. The cam is a comp cam. I gave the machine shop a paper that came with the cam that had all the specs on it for that cam. They currently still have that paper.

 

they have the cam card and still don't know what spring to recommend.....??....oh dear..........drive on outta there....
