Cheepy Three-Sixty build

Critique is fine. The seat width itself is .060" The S.S.R. is pretty steep and tall--(Just the way I like 'em) I ain't finessing them the way they need to be in order for the flow to hold on. The real problem here is the extreme back cut and angle of it on the G3 intake valve-pretty sure it does not compliment the Magnum bowl/valve seat approach. To be honest I really like the .100-.200" flow rates. Also at first blush the exhaust doesn't look all that great until you consider the 1.55" valve and subsequent sinking to achieve a proper seat form.

Considering these heads flow 189-191 cfm peak on this bench I'm pretty sure they'll work alright. Also this is a SF1020 that ALWAYS displays a good 10 cfm lower than you are used to seeing. Important thing here is If and How the flowbench correlates to the dyno.

Remember I'm using a small hydraulic flat with sub .500" @ the valve with the 1.5 Chev style rockers anyways.

Also the operative word in the title of this thread is "cheap" so I'm not going to invest my time into a $1200-$1500 porting exercise. J.Rob

Yes , great for a magnum head, and 'okay' for 2.0 intake valve. The exhaust you can sink a little on those and not hurt it so bad like with an LA exh port. I think in regards to flow and work invested...the 2.0 int hurt you because I'm thinking there isn't enough bowl and ssr work to take advantage of it. A 1.94 would actually do those numbers ...but I'm not scoping them out on the bench in front of me to see exactly where I'd do a little, not more than another hr across both banks, work to get that .300 into the 190's, it would bring the rest up and .500 flow would appear.

I don't think its the bench either, the super1020 usually shows higher numbers than my bench, by 4-7 cfm, ah but screw racing flow benches.lol The cam is small so to me the low lift is very important here with that sub .500 lift cam, .3-.400 lift matters more if the goal is optimistic. Thats my input relative to the heads and valve lift, not the entire build or idea of cheaply done and of course the casting may not be the greatest...but for what you're workin with , you're still doin good.
Im not a believer of magnum heads, did a few sets...but I won't waste my own time or dollar with them....now if that's what the customer wants , its their money...
