. It should be a nice upgrade compared to a stock slant.
The 225 slant going in my wagon has been decked 90 thou, head cut 10 thou, over bored 30 thou, 1.70/1.40 oversized stainless valves installed, mild port and polish, a stout cam installed which will work very well with the 4 speed, windage tray installed and of course a set of Clifford long tubes I found on eBay at a great price. This should give a CR of around 10 to 1 with a dynamic CR of 8 to 1, enabling it to run on pump gas. The seller knew they were for a slant but couldn't figure out the application (didn't fit anything he had so gave up on them). I knew as I had a set in the mid 80's and being stupid, sold them later on. Here is mine: I was mocking up a Dutra Hyperpak to see if a Sanden AC compressor would fit (it does!). You can see how the front 3 will route basically straight down in front of the PS box and actually passes through the front of and under the K Frane. The PS box takes up a lot of real estate down there.

Maybe Looks like your best option is the headers from Australia. The exchange rate is pretty good- for us lol! Another option might be to buy the exhaust flanges I see on eBay and fabricate a set that will fit with PS.
