Comp Cam Extreme Marine 226/236 @ .050
BG Sea Demon 750 DP
Edelbrock Performer Intake
I do not want to spin this over 5,500 RPMs
Last year after spinning a bearing(long story, stupid mistake)
I stroked it to a 496 and only gained 100 RPMs same compressing rato, cam heads etc.
I obviously have a bottle neck somewhere, and I am thinking the heads?
Edelbrock Oval Marine Heads 110CC
290 Intake Runner. What would this raise the compression ratio to?
I am guessing around 9:6.
Dart Iron Eagle. 119CC chambers, 305 Intake runners same size of valves as the Edelbrocks. Probably flows better out of the box. These can be had for about $1,500.
Any other IDEA’s
Thanks in advance for your input, and based on it will determine what I will purchase in the next few days.

The head will work but is not optimum choice. A nice aftermarket 300 CC runner would be a good choice. Low to mid lift airflow on these heads are exceptional so the use of a mild cam would make a nice flat powerband.
Head options would be the Canfield, AFR, Brodix, or the Edelbrock. I would go the route of hard anodizing for longevity.
