Keep the pinto out of this site!
The cast iron 2l escort is no better than the old kent head. Its junk without esslinger 3rd party specialty head. The l20b is raped for its rods by pinto people and twin cam 16v volvo heads are modified onto them by some to give the pinto some credibility. As for the L is you want to make over 200hp you have to turbo one or fit a modded ka24 head for the best bang for buck and even then you better start with the z20 engine for budget reasons. The ka24 twin cam head and 3 valver have 2 34mm inlet valves!!!!
