i downloaded the rules to my phone earlier in the week and today i look and seen they changed some options on the engine. One rule that peaked my interst was a 10.5 pump gas option. 362 inch limit 10.5 compression 93 octane 11 degree valve angle weight 2450 with a 5 inch blade. how would an 18 degree head work with this rule. kinda looks like the imca late model engine only they have a 23 spec head
