I did a search and couldnt find anything about this so I thought about asking this. I am getting my LS head milled .025 and porting and polishing it. I thought about changing cams and was thinking maybe B20 cams would work. If so would it cause to much of problem or is it impossible?

 

you could interchange the cams but you wont see any power increase........the cams are exaclty the same specs.

look into crower cams for the LS head.....they work really well..
