Vee_Que I misworded myself sorry, that are obviously a performance upgrade, but because of the dish in the pistons, to go higher in compression means making new pistons with an even smaller chamber in the piston, there's nothing to shave. Being an alloy head is an advantage and you can run something like 11.5:1 c.r easily without pinging, but I know of one head on a car and he didn't have the pistons made for high comp, only a copy of the stock repco pistons so he didn't know the c.r as it was built by an engine shop. What we do know is getting a cam ground to suit the evenly spaced intake and exhaust valves means grinding and welding a stock cam, or the blanks which possibly need work as well. You can get them ground but it obviously is more work than a stock cam ground from Clive cams etc. And of course with extra lift you decrease the valve to piston clearance which reduces the lift or compression you can run. The head design is nice. I've been told by b20 engine builders that the speedway guys used them, then went back to Volvo parts in order to get more power, the ports etc on a b20e can be increased enough to make more power combined with the obvious ability to go for more compression. Still a very cool peice.
Major Ledfoot If you look at the mods which Sweden's Lindquist Racing and Erland Cox, a guru with Volvo heads, have done with their B20 heads, the Repco port design makes sense. Lindquist's dyno figures are very impressive, however the engine doesn't get to peak torque until 5750 RPM.
Massey165 Have seen this head and yes it is new, the comments about pistons, cams etc and all correct. What you are buying is part of Australian motor racing history. The Repo Brabham company from my research only made 2 products, the Brabham engines and this head.

It needs to be advertised to the Swedes in Swedish and they will suck it up in a second There are very few people in Aus with the money to build a 20k motor including that setup for a vintage Volvo
VolvoMike Repco also made a similar head for the Holden grey motor. I believe around 220 for the Holden and 16 for the Volvo. Regards, Michael

VolvoMike I went out and had a look over this today. I see it only as a novelty item and not a true performance part as you could build a standard head up to make more power. I'd imagine the machining costs and build costs on top of purchasing this head would make it prohibitive for the output. Regards, Michael
deleted_user_2040 I reckon not even the best head porter on the planet won't charge as much as $6,000.
