pirate the 541 cylinders are a completely different animal. they are same bore and stroke but the flange location is different on the 541 it moves the cylinder head closer to the block creating more compression. however they are not just a bolt on and go. they have to be modified to work right. whe done you can make big power with big compression and the heads are fairly tough.

Compromise is failure on the installment plan.
