Last month's Hot Rod did a comparison test with a 11 cathedral port heads on a 408ci. I think the ProComps heads made the most peak power and did well in other areas as well.

Just make sure you match the heads/cam/intake/headers to the engine size. Bigger is not necessarily better.

I've got the GMHTP where they use them on their 417 stroker. They wanted them for compression drop and strength. Hit me up.

Once I got that issue, I looked at Procomps site and couldn't find any LS heads. Haven't tried since.

The Pro Comp's have a 1/2" thick deck, stock is about .400" thick, so you would be gaining about .100" of extra material.

would be good to know which head they copied as that is all pro comp does. Quality will be a issue like all their stuff.

Procomp seems to be tossing alot of their parts at magizine builds lately. I guess they are trying to get their name out there. They need to update their website to offer ALL products they supply to magizine builds.

You get what you pay for...look at the LSA heads or the LS9 if you want a cheap alternative to the L92 that is still square port and has the bigger valves. I just bought a set of the LSA heads they are cast from a stronger material T356 and roto-cast much stronger head than the L92.

Just my .02
