Whats the difference in the gt40 heads with angle spark plugs? Just for my knowledgeWell if you are going full hydro you won't have that issue haha. Not sure about the firewall, you probably will have to massage it with a hammer. Fullsizebronco forums has a sticky thread about speed density friendly cams.
And I forgot to mention, gt40 heads are a common swap, just don't get the gt40p heads with the angled spark plugs
