N42 head???

An N-42 head will fit on the L-24 with no problems, just bolt it on and swap over your intake and exhaust and go. Most of the N-42's were installed on the FI L-28's so it may have cutouts for the injectors. No worries, the intake covers them up and they will not be a problem. The N-42 is nearly the same as the E-88 head as far as compression ratio etc. but has one big advantage. It already has the larger valves. One problem with these heads was the bronze valve guides, they should be replaced with steel guides as the bronze tended to fall over time. Dropping a guide isn't much better than dropping a valve. So, check to see if it has steel guides already, and if not, install them and hardened valve seats while you are at it.

I'm not quite sure what head I have..Sould i be looking on the manifold, which has E88 stamped on it or what. It appears to be an N42, because that it what is stamped on the passenger's side of the block or is that the type of block I have..? I think what is confusing me is that I appear to have an N42 block and an N42 head is that possible? I don't know because I'm not sure where to check for each stamp (Head, manifold,and block)..
