KlubFoot Posted February 2, 2006 Report Share Posted February 2, 2006 I am looking to port and rebuild a set of E7TE heads. I was just wondering what all is done on a standard head rebuild, what should be done specifically to the E7TE heads, and what kind of work would need to be done to put in 1.90/1.60 valves? Also, could someone try to find me a diagram of a head so that I can familiarize myself with all the parts. Quote Link to comment Share on other sites More sharing options...
speedytang Posted February 2, 2006 Report Share Posted February 2, 2006 Go to Corral.net and do a search and you will find the complete porting instructions with nice pictures. You can upgrade with a nice spring kit from Summit Racing for around $130 that will get the heads to support high rpm and cam lift. Quote Link to comment Share on other sites More sharing options...
Dave1647545494 Posted February 7, 2006 Report Share Posted February 7, 2006 I won't tell you not to port those heads but you can pick up a nice used set of aluminum heads for around the same cash and make more power just a heads up....

KlubFoot Posted February 8, 2006 Author Report Share Posted February 8, 2006 The main purpose of this head rebuild/port is for me to learn something. I'm not trying to create the fastest car out there, and I know there are probably a lot better options for me to look into, but I want to be able to learn the basics before I go buying bolt on power. Also, a big factor being played here is my budget. Quote Link to comment Share on other sites More sharing options...
Guest Spoiler71 Posted February 11, 2006 Report Share Posted February 11, 2006 As far as porting E7 heads there is some good power to be found. The 1.94/1.60 Chevy valves are the biggest you should use. Most of the attention should be paid to the bowel area behind the valve and making that radius smother and consistent. The 1.84/1.54 Windsor valves will give you less shrouding and for the airflow the heads are good for they work fine. Get the gasket you intend to use and a sharpie and trace the outline of the port and work to match that opening into a consistent and smother transition into the bowl. Smoothen out the combustion chamber but try not to take out any material. The shape on the E7 is not bad to begin with. Quote Link to comment Share on other sites More sharing options...
Guest Spoiler71 Posted February 11, 2006 Report Share Posted February 11, 2006 Now when a head is rebuilt you will remove all of the hard ware anincluding the valve guides. Hot tank them to clean the casting and then magniflux them to see if there are any cracks. After that you will begin your porting and changing of the valve seats. Ford had the fore thought to give the head a 1.440 spring seat compared the the 1.25 of the Chevy and should not require any maching for your new springs. Locks, retainers, guides and seals should all be new too. Quote Link to comment Share on other sites More sharing options...
