    What parade? I really don't see the reason for being straight up patronizing, If the 8 psi(max) boost, lash caps, lobe geometry or anything else lead to a f*ck up - which of course is an option on an amateur build - I will contribute constructively and openly by posting the failure(s) in this...

    Admittedly, I am getting frustrated. Let me be perfectly blunt (I know I shouldn't, considering my measly 50+ trophy points): Ref. Thread title: I asked whether lash caps was a viable option. That's all I asked. I.e. is there some peculiar, weird english automotive twist that makes this...

    I don't have the info asked. However: 1.How can problems with the valvetrain happen in an engine that ran petfectly with excellent compression values prior to removing the cams, and that hasn't been turned over once yet? 2. Why, I don't understand how this warning ties with the one known...

    Yes, I plan to keep revlimit 6k. The turbo delivers max boost at 3,5k

    Ah. I think I see what you mean. There are smears of MoS/engine oil mix after very generous lubing of all buckets

    Well, the caps certainly adds another piece to the transfer of force, so it is not ideal. But I guess I can inspect caps and stems at each valve adjustment. The buckets are all identical and seems solid to me. They all have a "bump" of extra (wear?) material in the bottom centre, which is...

    Hi desertRat, I have used a company which entire business is camshafts. They even manufacture bespoke camshafts. Their camshaft/mods sits in almost every car in the National Street Car series. Several Pro rally drivers, brand dealers and other automotive professionals use them. They are...

    Hi Neville, smaller base circle/heel is alreeady given I would think as I had to increase shim thickness by 0.90mm+ all over the intake side. But what is your concern about the caps? It is just an extention to the valve stem, if anything with a larger area to apply force on the bucket.? I'll...

    Summary: Is lash caps an option for the RII? Yes. Lash cap used: 5.50mm ID, 2.50 mm cap depth, builds 1.10 mm to the valve stem Valve stem can be seen without cap here Here with cap on top of stem, resting on the stem, not the lock ring Cap matches well the bucket counterpart and simply...

    If I understand the manual correctly you can't change valve seats on these heads, they are hardened and ment to outlast the engine. I want to avoid cutting seats, also for that reason

    You might be right, have never been close to 0.93 gap with feeler gauges before. Will know in a few days when a shipment of 2.45-3.15 shims and 1.1 mm lash caps arrives. First thing I'll do is to fit a 3.15 shim to the intake valve having max clearance and see if I still end up with the same number.

    Thanks Pedro, I might just have to source make to order shims. One great advantage of buying from Australia is low shipping cost and surprisingly decent shipping time

    Hi, stock head. Yes 25mm shims are used. But difficult to find 25mm shims above 3.50 mm thicknesses

    Clearance example: measured 0.93 on a 2.80 shim. Set target clearance (intake) at 0.13 -> need 3.60 shim I bent my 0.63 feeler to a suitable radius. The 0.30 feeler on top flexed well enough. That said, I might be slightly off. Have never measured this much clearance before. But will mention...
