Default Best Header Gaskets

I did a search and didn't come up with much, so I'm just wondering what header gaskets you have had the best luck out of? I've been looking into getting copper ones but they are $35 so if there are any cheaper options that are just as good, I would like to go with those especially since I believe I'm going to be needing an opti soon

Thanks

Edit: I have Pacesetter LT's.

Percy's Seal for Good gaskets, put the set in two years ago, and still work awesome today. My buddy tried copper and those carbon header gaskets and switched to percy's and has no more problems. They seal very well.

The copper ones didn't seal worth a damn for me. Felpros are the only ones I've had luck with

Just installed pacesetters with coppers and they wouldnt seal for ****. I talked to Speed Inc and they will only use Mr Gasket Ultra Seal 5903 IIRC. Im going to try them and if that doesnt work ill end up trying to Percys. As if the install wasnt painful enough i cant get them to seal and throwing different gaskets at them.

I ran percy's with only 3 bolts on the drivers side for over a year without one leak. Just put a new set on last weekend, i expect them to last forever.

Im curious to that too i went to pick up a set and the guy at the parts shop hesitated to sell me the 1406 since there a brodix style vs lt style gaskets but i told the guy everyone is ranting about the 1406s. Same thing with the Mr Gasket 5903s which again are for a brodix. They are both d port but what makes them a brodix? Just want to be sure before i buy the 5903s which Speed Inc swears by on all there builds.

Thanks.

I think the only difference if the ones for brodix heads have bigger openings. I used those with no problems at all
