Twin cam Screamin Eagle MVA performance modified cylinder heads

    Screamin Eagle’s MVA cylinder head was fitted oem on Harley’s 120r engine. They were also available for sale individually which is how these beads started their life before being sent to Darren at RAMS Head Service in Windsor (Sydney) for performance work.

    Heads were shaved to provide 91cc combustion chambers. Porting work done, service and re-mod to seats, valves and stem seals. Bronze guides used. Valve work done including install of Av&V 1.65 exhaust valve. Installed AV&V VSK675T valve spring kit with titanium retainers with extreme heavy duty specs.

    Have oem Harley ACRs fitted too

    Recommended for big inch twin cam engines of 117ci and up. Could probably also work well in a high comp 113ci or 110ci.

    Built for performance cams of lift up to .675. Will make 140hp .

    I’ve not seen heads like this available for sale. If you price the cost of buying heads, and then adding cost of parts and labour with any decent harley head guy (of which there are few in Australia) you will know these heads are priced to sell. Receipts and paperwork come with them. As photos show, they are in excellent condition.

    $2,000

    I'd have to change pistons or use a very thick head gasket, did Fatslim have the flow data? Be helpful to have about now.

    No fatslim didn’t share that. I did try to get info from him but wasn’t successful 

    Darren at RAMs might have it. Murph can vouch for these heads. Made 140hp in 120r set at 10.9 on fatbob with 266 cams. So they are obviously very capable with the right combination of parts

    Good set of heads for someone that is contemplating a build for sure.
