Converting to a roller cam

No, usually the pushrods end up rubbing on the holes in the heads, because they are on a more severe angle, because of their short length. There is really no way to know if they are going to rub until you mock up the whole assembly. The rocker arm ratio has nothing to do with it.

That makes sense, when I get my heads back I will mock everything up to see if I do or dont. Is it very hard to clearance the holes?

as far as i know MRL only sells solid roller lifters.
I have been looking at the Hughes engine hydraulic roller lifters, which have a lower oil band for high lift cams.

Everywhere i have read praises the Lunati cam grinds. I have also called Lunati and Comp for my own engine build and the guy from Lunati impressed me, when he spent the time to figure out my needs and what would work. Comp basically shrugged me off.

Damn, I would really prefer to have a hydraulic roller, I will call to see if they have them though, because I am wanting to buy a set of the MRL lifters, seem good.

Yea my engine shop even recommended lunati cams, they have had really good luck with them. I have a cam that lunati recommended to me as well, but cant get that stuff locally.
