I will be installing a new GM crate SP350/385HP/400TQ engine into my ‘83 K5 Blazer with a 4” lift, 700R4 and an NP208 transfer case. I will be using the Blazer for street, highway and off-roading but not rock crawling. The SP350 engine has aluminum heads, “D” shaped exhaust ports with angled spark plugs. I would appreciate recommendations for headers versus exhaust manifolds that are fitment compatible with the SP350/D shaped exhaust ports with angled plug cylinder heads/700R4/NP208 TC for highway cruising to get to off-road areas. Anybody else have this same combination? Thanks
