I use bosch platinum 4's. Ive got a 70s block stroked with 90s vortech heads too. The plugs throw plenty of spark, but a spark plug change requires pulling the headers for clearance. Ive heard a lot of people running accel shorty plugs for the good clearance, but I dont know how they work performance wise.

With mine, I cant even get my socket on half the plugs without moving the headers.

That sucks.... sorry to hear that

Off topic, but your carb's too small, get an Edelbrock 750.

I like my low end power, a smaller cfm gives better results down in the lower rpms, where a bigger cfm gives better at higher rpms, carb is perfect for me, anybody know the accel plugs i can use in the vortechs?
