A new article with photos on the T/A & AAR rocker arms with a W2 / W5 rocker arm comparison
Back in around 85 I scored a pair of T/A heads but got no rockers with them. Thought I had struck gold, not so, I went to Dick Landy's place in Cali whilst on holiday and bought home some new W2 rockers/shafts, had rockers bushed. Well after about 2 days of grinding etc. to get them to fit I thought it would be ok, on track and up to around 6000rpm they were fine, over that I'd bend a few pushrods, probably me not getting something quite right on those 2. So W2's can be made to work if you can't get T/A's. You guys probably know all this anyway. Wish I had a bit more knowledge back then and used the stock heads, would've gone faster with a bit more rpm.
