Mike 57 Posted May 25, 2011 Share Posted May 25, 2011 What brand of head? Are they 3/4 reach with gasket? Are there clearance issues? Quote Link to comment Share on other sites More sharing options...

Mike 57 Posted May 26, 2011 Share Posted May 26, 2011 AC FR3LS would be a starting point, you can cross that to any brand you want. Quote Link to comment Share on other sites More sharing options...

ROMO Posted May 28, 2011 Author Share Posted May 28, 2011 Wow those where hard to find. I guess they are no longer making the FR3LS spark plugs but I found a site that had them for a penny each! thats rite a single sent!!! I bought 24 of them just because of the deal. They shipped today should get them by Tuesday. This is the website if anyone is interested: http://www.autopartstomorrow.com/search?...p;commit=Submit Thank you Mike again Quote Link to comment Share on other sites More sharing options...
