I am slowly building a 496. I plan on using some things from my 402...intake, headers, pan, timing cover, and heads. The heads are 292 casting. Does anyone know if these heads would be suitable? They are 113cc with 219/ 188 valves and pocket ported. Exhaust runners smoothed out and short side cleaned up. The cam is a hyd roller 242/248 .560/.578 110 lsa compression will be a bit over 10 to 1. The 292 casting is similar to the 820.
Does anyone have any experience with these heads? Thankyou
