I have a 1994 v6 sn95 with gt swapped t5, driveshaft and rear diff. It has a 1994 351w in it with gt40p heads. It will be running a holley carb once the carb is rebuilt. I was curious what gap my spark plugs need to be at. I was reading forms and it say a 1994 351w has 0.042- 0.046 gap but I want to make sure with the modification that is done to it since the headers are in the way of the spark plugs and it's a pain in the butt to get to the 7th cylinder plug

I have them at .046 so if that doesnt work I'll go up to 5.0 with some new plugs. Thanks for the help!
Honestly I’d just leave them where you have them. The only time it makes a difference is if you have a huge jump in gap, which doesn’t really apply here.
