I've always had great luck with Fel-pro's but toss the end rail seals and use a bead of RTV instead and make sure you get the corners with the RTV good also. Also, don't let anyone tell you to put RTV on Fel-pro gaskets. They have a sealer impregnated in them and using a sealer on them may conflict with what is in them and cause things not to seal.

The Fel Pros are a steel shim gasket. I sprayed them with Permatex copper coat and used Mopar black silicone for the end seals and on the corners. I let mine set overnight before I started it to let the silicone end seals cure. tmm

Thanks guys, just chkd Mancinis and they have a lot of Fel Pro's to choose from. have to figger out which ones. I may be pulling heads for some DIY porting on them.
Any idea how big I can go either in gaskets or on the ports?

Not all Fel-pro's are steel shim gaskets. They make a few different gaskets

Do you have something (a caliper) to measure your ports? I always like to match them as close as possible without any overlap into the port

Steve, I used this style gasket on a lot of "stockish" engines.....

It's close enough to the stock size that a little cleanup toward them, about a inch deep, will make a nice clean looking port. If you're pulling them to play with, keep in mind that the port matching, while nice looking, wont have nearly as much effect as a nice bowl clean up. That's really where the most improvement on stock heads is achieved imo.

Steve...you can use the steel shim-type intake gaskets, just not with aluminum intakes.

I really like the felpro print-a-seal type. I buy this sort of part locally. To see and know its correct and not damaged is worth the extra dollar spent.
