Default Big boost head gaskets

Thinking of using the SCE Vulcan head gaskets for my 427 getting built. What is everyone using? I need a 4.125 bore.

If I was going to do it go with the the lt4 head gasket in the size you need, If a blower motor you want a thinner head gasket due to pressure blow out if you try to lower comp on the motor. Plus the lt4 head gasket is thinner than the lt1 gasket...Robert

I used the Cometic with my last RHS 427 F1X build also one of the best head gasket out on the market. OP here go with no more than a stock thickness on the gasket. Don't go with a thicker than stock. Robert

Thanks Robert,
I don't see the stock gaskets having a bigger bore then 4.100. I talked with my engine builder and he also recommends Cometics with sleeved blocks. I am going to order the MLX Cometics .051 thickness. I think stock is .055.

Interesting setup. Would love to hear more about it! Maybe do a build thread on here?
