I am looking at a set of lt1 heads online and was wondering if the intake ports and water ports will line up on a TPI intake. I know the intake bolt angles are different but do they have the same pattern.
Any input will be a great help

The TPI intake ports are going to be a lot smaller, and the water passages in the LT1 heads need to be altered, along with the potential intake flange bolt problems.

There is a thread or two about converting LT1 heads, and all you need to do is search for it to get all the details.

The water passages on the LT1 heads to the intake don't need to be altered, they need to be there!

The LT1 intake was a dry system, no coolant flowed through it. Coolant got from one side to the other via a crossover tube in the back. I believe the heads will physically bolt on to a standard SBC but the coolant passages won't line up with those on the block.

The intake is really the least of your worries. The LT1 heads are pretty decent but they're not great. Your money would very likely better spent with a set of aftermarket heads for a typical small block. You'll have a lot less headaches in the long run.

Thanks for the input. I thinkd I will save my money for a set of AFR heads
