How much power am I giving up. 1205vs1206 HSR
So I'm running the AFR 195cc 1095 comp ported heads that match the 1206 intake gasket and my HSR is the older 1205 intake that would need welding to get 1206. Should I sell the HSR and get a newer portable 1206 one to match the heads or just lightly port my HSR and run the 1205s? How much power am I leaving on the table. 355 camp cams custom grind 224-230 .570s lift 112. I don't want to spin this short block past 6k often with the stock crank.

Also I see the 1206 don't match the 1095 comp AFR heads perfect. I cut a very small amount of the 1205 gasket and it matches pretty good.....as long as I have all the blue silicone left on the gasket do you think it will seal alright?
