Ported and polished heads and a pair of busa pistons

I don't think i'm gonna get around to being assed to fit the heads and busa pistons on my SV and i think i'm gonna give up tuning it any more, i'm happy with it the way it is

I've done a DIY porting and polish job on them opening up and polishing the exhaust ports, de burring the inlet portd and fitted new valve seals, exhaust gaskets and lapped in the valves

the only thin i dont have for them is 3 sets (6) collets which hold the valve springs down

I've used stainless bolts for the inlet manifolds and otherbits

I think £80+ postage for the heads and £40+postage for the busa pistons, search svrider for info on fitting these

I'll post some pics later

So whats the advantage of this?

Do the heads have cams fitted? And if so which ones?

Better gas flow in theory, the expanded exhaust ports will better flow out and polishing them will help stop coke build up and deburring the intakes should stop turbulent flow in

No cams with them

Sold anyway

The advantages of the pistons is they are lighter and stronger, less rotating mass and they're not sold

Hah, I thought you'd gone quiet on that
