Bumpers and headers for zz4 engine??

[johnny idaho]

Just finishing up a build on my 72 chevy 4X4 I installed a zz 430 crate motor with the new style aluminum fast burn heads they have alot larger exhaust port than the old heads, So now my headers are barely covering the exhaust port, Do they make any adaptors or does anybody make headers for this application??, I need headers with at least 1 and 3/4 diameter tubing. I also am looking for custom bumpers I want a heavy duty winch bumper on the front that also looks good, Thanks, Johnny,, I will post some pics tommorrow
