T/A heads
I managed to get a pair of T/A heads back in my day for the 340, thought they were better, spent a lot of time trying to get W2 rockers to work cos I never got the rockers with them, which I almost succeeded in doing, but motor kept spitting pushrods at over 6k rpm. Wish I would've known then that they were nothing special and the stock 2.02 heads I had were as good or better, mine didn't look anything as good as those with no bowl work just a lap in of the valves. No wonder I only made 368fwhp with them on a 10:1 340 with a .590" sft cam, race hdrs strip dominator and an 850DP.:(
