Talking 911 Head Before and After Photos

Sent my heads off the Henry at Supertec to get the heads in usable shape. I knew it was leaking around one of the intake valves and 5 of the exhaust valves. Oh yeah, and they were pretty nasty looking...

Here are the before pictures:



Please note that my instructions to Henry were not to help me build a show motor or a race motor. My instructions were based on my latest project, a 1972 911T targa. It needs a motor and I have a supposedly good 2.7 that I am doing a re-ring topend on to replace the 2.4 that only runs (but still runs) on 4.5 cylinders. I am on an extremely limited budget and my goal is to build the motor to last 30k-50k (probably 6-10 years as my second 911) miles so I can drive it instead of just letting it sit in my garage like it has the last 7 years. Budget, budget, budget. My instructions were something like "Do the minimum so I can drive it a while." No porting, no polishing, no twin plug, no new parts unless the old ones are out of spec and unlikely to last for the target mileage...

My next rebuild will hopefully happen BEFORE I need a new motor and I plan to take my time and do everything perfect. This time it's about getting something instead of nothing.

Anyway, Henry fixed me up. It was a good news/bad news thing. Good:
- Heads had had a recent valve work guides installed and so new ones weren't needed.

Bad:
- All exhaust valves were bent and needed replacing. Although the valve guides were OK the previous valve job was crap.
- The heads were actually 2.4 and needed a chamfer machined in to clear the larger diameter pistons.
- Needed some exhaust studs replaced and inserts

Thanks to Henry for helping me get my parts in usable form. They came back looking better than I expected based on my instructions to him. He was a pleasure to deal with and I really like the product. It's always nice to get a little more than you expect rather than less. I can't wait to get my car in good running shape.

Here's a few quick after pictures of one of the heads. I think they look better in person than the pictures.




Happy motoring,
Rob

Oh, here's one of the car it's going to go ing while I'm here.
