I just bought a set of shorty Hedman headers for my 350 SB. I got the flanges with it but no gasket does any one know were I can find a gasket kit for them? I was also wondering on how hard do u all think it would be to install them myself ? One more thing I need to get bolts too were would I go on finding them ? Info I have a 350 SB with TBI and it has center bolt valve covers. Its in a 89 blazer with 4" of lift and tru dual 40 sieres flowmasters with no X or H pipe. PS: I was wondering if paying 30 bucks for the headers and flanges was a good deal?
