502 EFI Cam selection
 

I have a 1995 24' Fountain CS. I currently have a 502 EFI that was stock w/ 415HP. I added a M1 Procharger and up'd the HP to 620. I have to tear the motor down due to a blow head gasket that rusted my cylinder walls. While I'm in there I want to change the cam and heads. I have a big block car w/ World Products Merlin heads I have been very happy with. Would these heads be good for my 502? I also heard I had to be careful in my cam selection because of the EFI system on my boat. I dont want some huge loppy cam, just something to allow full benefit from my Procharger. Any suggestions? If so, why do you recommend what you did?
