Re: Which Header ?
I have used both Jegs and Summit headers for different vehicles. I used non coated so I can't comment on the quality of the coating but the fit was good with no modifications ( Small Block 1970 Monte Carlo, Big Block 1977 K10 and Small Block 1976 K10). Pay attention to tube sizes one of the reasons that they can be less expensive is the smaller tubes which also helps in fitment. For me it worked out fine since the vehicles were all daily drivers or tow rigs
