Hey all. So, I'm in the process of mocking up my 505 stroker...440, .030 over, etc...(Factory iron block, TrickFlow aluminum heads)
I have Fel-Pro 1009 gaskets, and I drop one on the block and to my dismay, the fire ring is over-hanging the factory chamfer by a noticeable amount. These gaskets are supposed to be 4.410" in diameter. Everything I am reading says this is a no-no situation because it will trap combustion pressure under the ring and lift the gasket...
So, what are my options? Cometic MLS 4.500" ? Rubber-coated Copper 4.500"? LS swap? (J/K)

Some blocks have a gigantic chamfer in the top of the bore and all I know to do is go to a gasket with a bigger hole. My friend recently had the same problem. I feel your pain. The Fel-Pro 1105 is real big, gasket hole 4.59. I wonder if they have anything in between? If not you will have to change brand.

If you think the block is bad check it out on the head. Edelbrock head fit is terrible

With Trick Flow heads you should go straight to Cometic gaskets. Don't bother with any of the cheap stuff, order the correct parts and do it once. x4! I tried Fel-Pro's with my 505 build initially and had issues. No issues with Cometics (I've used 2 different thicknesses) over the last 9 years. Lots of abuse and a rowdy jug!

My suggestion is anyone considering the Fel-Pro 8519 look into the 17059 Marine gasket instead: https://board.moparts.org/ubbthread...38/fel-pro-17059-marine-head-gasket.html
