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.

OEM ovals will support this CID to 5500 rpm. We run OEM ovals one several engines in truck pulling engines and turn 470CID to 8500 to 9000 rpm. 2 out of the last 3 champions have had ovals.

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.
