1262's are nice gaskets but have no provision for an exhaust crossover. I like 1250's which have the crossover provision but are not very large. They did fit my TFS TW heads before I ported them.
If you still have your old gaskets and if you still have the exhaust crossover shields, keep these. I cut an opening in my 1262's for this graphite heat shield. It works great.
I am going to try the real thick felpro gasket for racing. It is .09 thick without the blue silicone around the ports. I am not sure l like these since I have sucked a bunch of these over the last 3 years.
Let me know what you end up with.
