Mr. Bugaj, I do not run EFI; however I would recommend Heads Up Cylinder Heads for your friends project, if he is looking for a quality Cylinder Head at a reasonable price. Many other engine builders have been mentioned and they might be a consideration depending on the level of performance and money your friend is willing to spend. Mr. Layer does CNC cylinder heads for a good number of the premier engine builders out there, who then put there personal touch on them; however with the HP rating on the LT-1 where it's at, I do not believe it really matters where you go, unless you want HP on the combo, lol!

PS: Mr. Keown, please keep "bolting" motors together, lol! Your time is actually worth money and you have too much class to bother with people who posess neither.
