the same cylinder as the standard metra (produced by airsal) but punched out a lil more!

specially formulated BRK single 1mm ring piston developed just for this cylinder.

6 transfers, 2 auxiliary exhaust ports, and a nice large exhaust port and now with a single ringed piston!

the head does NOT come with a decomp valve so be prepared to re-use your old valve!

around 61.5mm thick if you need that info for some hacker n tuner application
