I now this has been beat up but I cannot find what plug a econo w2 head uses.

I have been using Bosch platinum, go back to these or another type?

Thanks in advance

I like NGK R-5672A-8, -9 or -10 depending an your compression ratio.The -8 is hotter, -10 colder.These would be for race use.I'm currently using the -9. I like the NGKs because they're a little easer for me to read.
