Really don't wanna fly cut
 

Right now cam only 98 car with untouched 806 heads my dad's had ported .040 milled 241s he is pulling off his car. And I'm gonna try to work out a deal for them.. I had a tsp 231 237 .598 .596 cam with stock bottom end.. And was thinking a .040-.045 head gasket. Do I need to flycut?? I know it would be recommended but I do plan on spraying the car with 100-150 shot like I am now and don't want to weaken the integrity on the piston itself..

You would have to measure and report back with said measurements.

I don't think the pistons will be a problem for you even if they were fly cut.

Yeah I figured I'd need to measure but didn't know if anyone with a similar setup could chime in

You might want to open up the Ring gaps...

No detonation so far I have it tuned very safe on the juice
