The 1947 - Present Chevrolet & GMC Truck Message Board Network - View Single Post - AFR Angle Plugs '77 4x4 and Headers... What's the answer

L98 Iron (as found on 3rd gen camaros/firebirds) heads are straight, yes (got one in my GTA). L98 Aluminum (corvette) heads are angled. Some aftermarket heads are very angled. The ones I have are "L98 Angle" 1038's from AFR.

I'm "pretty sure" these hedman 69099's will fit. D-port even (which the AFR's have). I'll post back a reply if they do or don't. Will install them in about a month when I get back to the US. Problem is, is that I'll only be back for 2 weeks, so don't have time to do it again.
