Ok ,
just to go down the road a bit .
Which head gasket is good for the Tflow head ? Felpro 1009 , 8519 or buy the Tf cometic which doesn't have a 4.410 bore ?
I understand the Felpro max wedge intake is fine , or go Superformance .
I also need to buy TF rocker shaft studs , but my Crane Gold 1.5 rockers will be reused .
I currently use a 0.039 x 4.410 Cometic but may economise with the felpro if it works .
I know economy and racing are mutually exclusive but by the time parts arrive I am at double the US$ cost .
thanks again ,

Tex
