Groovy, thanks for that.
I was aware of the tappet problem. I was chatting to a guy here in Aust who build touring car engines, and he's apparently got a solution for it - although it sounds a bit.......agricultural? He seems to think it's a combination of revs and big lift, which cause the problem because the geometry of the valve train get's all out of wack.
The valves "float"? Float meaning bounce?
Yeah, I was looking at using GTiR posts in place of my HLA's, but it's a money and time thing. The recesses in the DE head for the HLA's is bigger than the GTiR recesses, hence I was considering making up sleeves. Problem is that it's pretty expensive to buy all the gear and I couldn't find anyone else who had done it. I didn't want to spend big $$'s to be a guinee pig, so I had the cams ground for the HLA's. I'm planning a full house grunter for 18 months from now or so, so I'll need to sort it out.
