Probably so Roger--I think it was those alum heads that back in the 90s for non LT type stuff(reverse coolant flow) that we put 2.02 and 1.6 valves in with just some touch up around the seat area in the ports-ran extremely well on the TP manifolds-I don't remember if they had different manifold angles but seem to remember that the bolts were at a different angle and maybe a couple were not used
