I like those, they're well designed.
A lot easier to deal with than the 3-peice Stage8s.

I also use the fel-pro's.....But with the LE2 heads "raised" exhaust ports, every header gasket i've seen has to be matched to the head ports(a dremel with a stone works well).....then "also" in almost every case, the upper end of the header flange and primary tubes NEED to also be ported out a bit for perfect flow through(from head port to header tube)..........a buddy of mine that just threw his LE2 heads on without matching his header gaskets and headers themselves picked up nearly 30 Peak HP after it was corrected at a later date.................Joe

Ive used percys and they worked OK, but im super **** about header leaks and the tinyest leak will drive me crazy. The absolute best header gasket money can buy are the Earls. they have a hard aluminum frame and graphite/aluminum composite inserts that are AMAZING. never had a header gasket seal and stay sealed like them. Ive NEVER had a blow out and NEVER had the standard bolts (not locking) lossen and they fit my LE3's with no problem. Ive been running them for about 3 years now and LOVE them. I had them on my TPI engine and when I did the LT1 with the D-ports I just bought the replacement inserts and reused the aluminum frame.

Yeah I was looking at those too. From what I can tell the regular SBC header gaskets have bigger openings than the LT1 gasket openings.
