Good morning, yes I am. I'm looking at Scat c25 or C35 camshafts from VWH. Cant find any flat top pistons except from aircooled.net and they are out of stock and P&P is tough. VWH has the recessed piston tops but no flats. Stateside is expensive. Think I will change the springs regarldess, I'd like to avoid using shims and longer push rods if possible and avoid changing rocker arms. still thinking about CR recess vs flat top.
