I just did a compression test and it was 160-155-155-160. Looking good there but my 22R head needs some work. The exhaust manifold stud holes are stripped and the stock exhaust manifold is cracked so I figured I would just rebuild the whole top end. I'm looking at getting the LC stage II
cam and there cam kit with all the springs,guides and retainers.
I don't think I will be porting the head and I don't want to swap my head for a 20R. I will also be using the stock intake and installing a Weber 38 and header.
The only thing I'm not sure about is the valves. Should I go oversize or just get the ss 45mm intake and ss 37mm exh ? They have ss 45.5mm intake and 37.5 exh.

Would I get any more power or performance gain from the 45.5mm and the 37.5mm without porting?
