Ok here is a deal,
I have Twisted Wedge heads that are milled .035 or .040 (not sure because guy who sold them to me don't remember exactly)
I have plan build nice 306 with my block and good 306 kit
I going with 9:1 compression (8-12 psi from turbo) but problem are my heads because those heads are milled and if i use them i will bump compression .6 to .7 so it will be 9.6 or 9.7 which i don't wanna
I have 4 solutions
1. Get pistons that are 8.3:1 so with heads compression will be 9:1
2. Get thicker headgasket
3. Machined combustion chambers to get previous cc
4. Get new TW heads with stock CCs
I don't wanna spend a lot of money so it have to be on budget but good
Don't post "sale TW and get AFR" or something like
Or don't build 306,build 331 or 347
