alright well now that my post has turned into a flame fest let me get this strait. seems like most people like the b16 head with a port and polish. fairly consistant with what HT said so it sounds like a good idea. as far as boosting goes should i switch out to a lower comp piston, say 9.5ish. should i bother sleeving the block with darton or whoever, my goal is above 11's so im looking prolly over 300hp. correct me if im wrong im just going off what i see on other cars. mydel sol should be lighter than alot of cars so maybe not so much HP is necessary. thanks again for your responses in advance
