Shorty header install?
Well its finally warming up enough here to work on car, other than wax and clean, no heated garage yet. QUESTION-How hard is it to install shorties and anything I have to be careful of? Any special gasket better than another? Any pics? Thanks :cheers:

Re: Shorty header install? (bizaro1234)
I asked a similar question about a year ago and was told by many people that I should wait until I can get a set of full length headers, that shorties have NO performance benefit over stock manifolds.. I was shocked, but it seemed to be the consensus... It was ok, too, I only wanted to do the job once, it looks like a serious PITA :yesnod:

The LT1 stock manifold are cast aren't they?
Anyways, GM used shorty tube headers on the L98 Vettes, vs. cast manifolds on the Iroc Camaros, and they claimed higher HP output. The motors themselves were exactly the same.

Long tubes aren't legal here in CA. but the shorties are. I got mine used,($250) but still new from someone who bought them and then decided to go to long tubes. They do help. See my dyno's. The hardest part is getting the EGR bracket bolt undone from the back of the engine. It can be reached best from underneath.

Re: Shorty header install? (bizaro1234)
What ever header you chose shortie or long tube. DONOT use the gasket they send you with the header because they are junk (burnedout) and will eventually leak. It is a pain in the ars to replace the header gasket. Therefore use only Felpro gasket. This has happened to me and I replaced with Felpro gasket, after that I never have header gasket problem.

Unless of course you live in California, then you just have to make do with what you can.
