Nnnnoooo...not a old "509"!!!....old school lazy ramps, too much overlap, and non-split duration. Still too much for a stock low compression engine. Until you bring the comp. to a real-world 9.5 or so, all these goodies aren't gonna do anything.
split pattern cams are aimed more towards poor exh flow ratios and or exhaust manifolds, his heads are ported and if done right...the ratio need not necessitate a split pattern cam. fwiw
