Saxo vtr head?

[SaxoVTRben]

i have the late silvertop engine 98bh 3plug, 52 plate vtr. is there a better head for this model that anyone knows of? ie that goes better with cams, ups the rev limiter and is stronger....etc

I've heard some people fit 106 XSI heads to their VTR block.. as the XSI uses the non roller type head (more rev's) and larger valve sizes (more air/fuel) and they use a 'big bearing' camshaft.. which as standard is wilder than a VTR camshaft.

do you know if its a straight fit or needs work and if so how much?
