head bolt bulge in runner?

This is a set of 302/318 heads that I just did a week ago

Int. 1.78 Exh. 1.50

.100 76 77
.200 111 113
.300 175 122
.400 201 126
.500 204 128

this was machine cut and a good valve job only, no hand grinding.

This is a set of 915 fully ported with 1.88 intake valves

.100 94
.200 180
.300 222
.400 241
.500 280
.600 283
.700 278

This just gives you something to judge how well your doing, and progressing.
