I got a nice set of 188 rectangle port heads and want to put them on my 1990 gen IV block. I heard I just need to use the Fel-pro 1071 head gaskets. Will this combo work?

That will work however it is not a marine head gasket. You may be more interested in the 17049 or the 17046.

Personally I would go with the 17046.
You kind of sound like using those heads with that block would need that particular gasket. Those heads were made for the Mark lV block.

Thank you picklenjim! I was searching the forum for engine/head configurations and got confused! All the gen IV, V, VI stuff and then add heads to the mix, some fit some don't, etc! Whats the difference between the 17049 or 17046? Summits website does not really tell any difference? Thanks again!

It states that the 17046 is teflon coated. I've always used those and have never had any issues. It also states they are actual marine head gaskets.Those 188 heads were made from '70-'71 and the mark lV blocks were made up to '90.
