I got under the car and re adjusted the valves. I found one or two fairly tight exhaust valves [about .004 cold ] so I went through all of them and set them at .006/.008 per the "book". The engine jumped to life when I started it up and most of the choppieness is gone. I think it's a matter of some more tuning and things will be even better. I do get a slight drop off in the idle when I slow to a stop but it tends to rest at 800 +.

One thing about the rebuild. It's suddenly got a real grunt and I assume it's the Webcam/euro pistons that helped here. I moved to 1.8 liter SS HE's and Bursch road exhaust and it's a lot loader [a notch less than a Harley] than the 2.0 HE's w/Bursch.

Any opinions out there on this?

do you have fi or carbs? what year is your car?

Not too sure why the exhaust would be "that" much louder if the same type muffler was used...the extra compression and tighter motor might have something to do with it since you are getting a better "burn"????

i think my header w/muffler is quieter than when I had heatexchangers and a bursch muffler

74 2 liter D jet F1

Uprated oil pump, Euro Pistons[w/new matching cylinders], Webcam by Rabyand dual air intake. Everything else is stock rebuilt from the crank up.

My thought is the cam , with better lift/duration adds to the sound of the Bursch...just a guess.

Can one use the wrong exaust gaskets or do the 2.0 and 1.8 have a different bolt pattern? I don't have the old exchangers to compare.

The 1.7,1.8 and 2.0 gaskets are the same at the heads.

Sounds like a cool ride! I have heard good things about the webcams. Congrats! Drive it like a Porsche!

Understood...I am refering the the gaskets at the exhaust not the heads.

Ah,,,,,,,,dang, you know, I "think" they are the same? At least up to 74'? My mind, I cannot remember.

the 2.0 h.e. to muffler gaskets are different than the others. they have a wider bolt pattern.
