miss?

[gr868]

i have a problem with my 355 chevy it idles rough and when you have rpms steady it has a miss but when you accelerate it goes away i am stumped i thought it might be a burnt valve but pulled the heads and all lokks well any ideas?

Sounds like a text-book vacuum leak to me

that's what i thought but no sign of one but i will check it again when i get my heads back from the machine shop

well after spending 220$ on a valve job milling the heads flat and new z28 springs got my heads back i think my problem was a vacuum leak because the intake gaskets were trashed when i pulled them so i did a little research seems alot of people with vortec trucks are having problems with the stock gaskets i was wondering if anyone here has used the fel pro gasket #1255 with any success?

the fel-pros are better--they have a metal sleeve at the bolts to limit crush. the most important thing is to properly torque the bolts to the right 3-stage values and the right order.

Put the pics on a photo web site. webshots or photo bucket. Just follow the instructions it's real easy. Once your pics are on the web;

Get the pic up on your screen after you have put it on the web and right click to open an option box.
Left click properties (last one down).
Highlight & copy URL (will end in jpeg, normally third option down)
Now put where you want the pic in the thread your posting in.
put your saved URL between the
e.g. (with no gaps)
Post reply and the pic should be there.
