2) Same questions for headers
3) Is that motor considered a Gen 1 or Gen 2 SBC? (trying to shop Summit by motor for pricing)
Sorry, I am not much for mechanical work. I stay with body & paint usually. Thanks for any help you offer.

1. The center 2 intake bolts on both sides of the intake are angled differently than the perimeter bolts heads. I would just order an intake for a 87-95 truck and you should be fine.
2. Header should fit anything small block up into the 5.0/5.7 Vortec, just make sure it fits your vehicle and any emission requirements.
3. Those heads are still concidered Gen I.
Gen I-All small blocks from the first one till 02 excluding the LTx and the LSx, but does include the 5.0/5.7L Truck engines.
Gen II- LTx engines found in mid 90's F-body cars, Caprice, Impalla, Corvette
Gen III/IIII-LSx engines found in late 90's-up Corvettes/F-Body Cars, 99-up 1/2 ton and 00-up 3/4-1 ton trucks (4.8, 5.3, 6.0, 6.2L)
