can anyone tell me if I can get better hp by putting mild cam in kombi 2ltr and swapping standard 2ltr heads to 1800 heads for bigger inlet valves ,or is it just better to stay with 2ltr heads?,cheers,Jack.

Go with the 1800 heads.I had 1800 heads on mine and noticed a big difference to the top end.Bottom end torque was down a bit though,but not really that noticable.

Maybe try some higher compression pistons with the 1800 heads too... and/or a set of kadrons or IDF's.. depending upon ya budget and performance needs.

Either set of bigger carbs will easily get back ya low end torque, and the thing will go like clappers right through the rev range due to the non-standard heads.

And all this will benefit from said mild cam.
