I was told to ask you for advice on head, cam, and headers, for my boat. I have twin 454 efi magnums in 28 ft obsession cat. Looking for some good power gains without blowers. I was looking for aluminum heads. I had my eye on the afr 315 cc heads. Would they be too big for my application? Id like to be able to run 89 octane. Also want to upgrade the cam. any sugestions???????? And last but not least headers??????? I dont have an issue with budget, I want the best combination package that I can get. Ay advice would be greatly appreciated, Thanks, Mike

obsession/Mike,

The best way to get ahold of Bob Madara (aka "rmbuilder") is at Marine Kenetics in New York. He engineered my head & cam combination/selection for my boat engines and I am very pleased with the results. He has helped several here on OSO. His Phone: 585-654-8583

Thanks for the number kaama
