Does anyone know if the TVIS and nonTVIS 16v 4ages have different pistons for the different valve cutouts?

Revhead, got different part numbers?

Yep they do. Non tvis have a larger cutout and a raised middle section, also higher compression.

Can send pics if you want.

Thanks

The reason is I have bluetop cams to put in my smallport 4age. I just wanted to know if the pistons and valve would collide since the bluetop has more lift.

Out of interest could you send the pictures to thecookiekiller at hotmail dot com. Thanks

cams will go in fine mate.

Many pple have fit big port cams in their small port engines. Easy as.

They will go in sweet like evlgtz has said. Ive got a big port head with a small port block going on it. Ill send the pics.

If you are interested, the guys on club4ag have covered this quite a bit.
