Your 95 is most likely a vortec and it has a much different intake.

96 is when they started vortec. 95 was the last year they used TBI in trucks.

Will the LT1 intake fit my standard SBC heads?

I have test fit the intake on several different types of heads including stock early and late bolt pattern, Trick Flow, and AFR. Due to the dozens of heads available for the SBC I cannot test fit them all.

Some heads that have had problems are World Products Dart II and Sportsman II heads. The coolant ports and EGR port are much larger and there isn't enough intake flange to cover the larger holes. Seems like to me some material would need to be welded to the LT1 intake to provide additional coverage of these larger holes.


Will the LT1 intake fit Vortec heads?

No, it will not fit. The intake mating flange is too narrow to cover the tall ports that the Vortec head uses. Here's a cutaway picture with a standard SBC intake mated to Fastburn heads. Fastburn heads are drilled with both standard SBC and Vortec bolt patterns.

The LT4 intake will not fit Vortec heads either. This is due to the Vortec bolt pattern being way too high on the head for the intake. The LT4 intake can be adapted to Fastburn heads because they are drilled for both standard and Vortec bolt patterns. So an LT4 intake would still require a bolt pattern change to std gen1. Some port matching on the LT4 intake will be required when using Fastburn heads.
