1.92 heads

Know a guy with a set of 1.92" cast heads that have been ported and polished. Is $200 for the pair resonable? We haven't talked money but that is what I am going to offer. He might ask for more, what should be the limit?

Re: 1.92 heads

Do some research and see if that head is what you really want. Then, who did the porting, a pro or some tweaker? Professional port jobs are $pendy, and if his are done right he will laugh at $200. But if they are 1.94/1.5, then it was probably the tweaker. I would do some homework if I were you.
Someone here wrote about some Vortec heads they scored for cheap. That sounds like a excellent option.

Re: 1.92 heads

Well, there are several versions of the 1.94 Chevy head. Check with http://www.mortec.com to check out the casting number. If the seller can't figure out what the casting number is for you don't even go look at the heads. Anyone with a set of performance Chevy heads for sale will know the casting number. There are several things to know about Small Block Chevy heads. Combustion chamber size ususally 64cc or 76cc and wow what a difference the combustion chamber size can make on compression ratio! If you get the compression ratio to high, the engine might not run with 87 unleaded octane gas! Do the heads have the seven exhaust bolt hole pattern? What about the accessory bolt holes for the alternator / air conditioning brackets? What size spark plugs will work, some older heads need spark plugs with a compression gasket. Are the heads Heavy Cast or Light Cast? If you don't know what you need in a Small Block Chevy head, then most likely your going to purchase something that might not work for your vehicle application. Trust everyone, but cut the cards.
